What is the GV series and what is it designed for?

The GIGAVAC GV series is a hermetic DC contactor family delivering economical high performance. It preserves the quality standard of the flagship GX/MX/HX families in a more affordable package. Both ceramic and epoxy construction options enable application-specific cost/performance optimisation. It is designed for EV pre-charge, automotive power distribution, marine electrical systems, off-road vehicles, energy storage (ESS), forklift/AGV and hazardous-area industrial applications, covering 100 Vdc up to 1000 Vdc switching.

How does the GV series differ from other GIGAVAC families?

The GV is built specifically for applications that need an economical solution. • GX/MX/HX: flagship premium families — top features at premium cost. • GV: economical yet high-performance — same hermetic quality, lower cost, broader application flexibility. GV also offers both CERAMIC and EPOXY constructions for cost/performance tuning, and covers 100 V to 1000 V from a single family — a real sourcing advantage.

Which GV models exist and what current/voltage do they cover?

GV spans 100 Vdc to 1000 Vdc switching with continuous current from 150 A to 500 A. LOW VOLTAGE (100 V) — automotive and general power switching: • GV12 — 200 A, EPOXY, NO • GV14 — 400 A, EPOXY, NO + optional PWM • GVL14 — 400 A, EPOXY, latching MID-HIGH VOLTAGE (800 V) — EV pre-charge and industrial: • GV22 — 200 A, EPOXY, NO • GV200 — 500 A, CERAMIC, NO (EPIC® hermetic seal) • GV24 — 400 A, CERAMIC, NO + PWM HIGH VOLTAGE (900-1000 V) — ESS and HV distribution: • GV21 — 150 A, 900 Vdc, CERAMIC, NO • GV35 — 500 A, 1000 Vdc, EPOXY, external-PWM coil • GVB35 — 500 A, 1000 Vdc, EPOXY, standard coil NO

What is the difference between CERAMIC and EPOXY construction?

GV uses two insulation constructions: • CERAMIC: GIGAVAC's patented EPIC® ceramic insulation. Preferred for high voltage and aggressive environments. GV200, GV21 and GV24 are ceramic. • EPOXY: a more economical hermetic seal that delivers consistent industrial-grade performance. GV12, GV14, GVL14, GV22, GV35 and GVB35 are epoxy. Both constructions retain hermetic sealing and the same protection class — only the structural insulation material differs.

Can the GV series be used in hazardous locations?

Yes. A key GV advantage is hazardous-location certification. It is approved to UL1604 Class I, II Division 2 and Class III. That makes it suitable for oil & gas operations, chemical plants, marine (SAE J1171 ignition protection, ISO8846 flammable-gas protection), explosive dust environments (flour, grain, coal) and aerospace sub-systems. Specific variants — notably GV200MB — are tailored for these applications.

Which certifications does the GV series carry?

GV carries a broad certification set: • UL508 — Industrial Control Equipment • UL1604 — Hazardous Locations (Class I/II Division 2, Class III) • MIL-STD-810G — salt-fog standard • SAE J1171 — marine ignition protection • ISO8846 — marine flammable-gas protection • IATF-16949 — automotive quality management • RoHS and CE Mark of Conformity IATF-16949 makes GV the preferred choice in automotive OEM supply chains; UL1604 makes it the go-to family in hazardous-location industrial applications.

What are the latching and PWM variants in the GV series?

Beyond the standard NO models GV includes smart variants: • GVL14 — latching. A momentary coil pulse changes state; the contactor then holds position with no coil energy. Ideal for passive battery isolation, emergency disconnect and coil-power-critical duty. • GV14, GV24, GV35 — PWM coil options. Full power on pick-up, reduced power on hold. Cuts annual energy consumption in always-on contactor applications. GV14 and GV24 use internal PWM; GV35 needs an external PWM driver.

Which mounting types does the GV series offer?

GV offers four mounting options: • 1 = Upright — standard underside panel mounting • 2 = Side — side mounting, saves space in narrow panels • 4 = PCB, M8 — direct PCB mounting • 5 = PCB, M8 with barrier — PCB mounting with added barrier protection The GV is position-independent — all models can be mounted in any orientation, giving designers panel-architecture freedom. The PCB options are especially valuable for manufacturers integrating contactors directly onto electronic boards.

What is the difference between GV200 and GV200MB?

GV200 and GV200MB share the same body but target different segments: • GV200 (GV200CB-1, GV200FAB-1, GV200MAB-1): standard 500 A, 800 Vdc EPIC® ceramic-insulated contactor for general industrial and EV use. • GV200MB: the marine / hazardous-location version of GV200. Meets UL1604 Class I & II Division 2 and Class III, IP67 with at least 30 minutes of temporary submersion, SAE J1171 ignition protection and ISO8846 flammable-gas protection. Designed for boats, offshore platforms and chemical facilities. Both models offer 500 A, 800 Vdc and 12/24 Vdc coil options.

What is the GV35 External PWM and how is it used?

GV35 is a 500 A, 1000 Vdc EPOXY contactor that requires an external PWM driver — there is no internal PWM coil, so the system must implement the PWM drive circuit. This gives flexible coil-drive design (application-specific tuning), full control to the system engineer and a cost advantage (no internal PWM). A dedicated application note ("Driving the GV350 with External PWM") covers PWM circuit design. If you prefer internal PWM, evaluate the 800 V GV24; GVB35 is the standard-coil (non-PWM) version.

How is the GV series used in EV pre-charge circuits?

GV is an ideal choice for EV pre-charge circuits. A typical pre-charge architecture uses: • Main contactor: GV200 or GV24 (800 V class) • Pre-charge contactor: GV12 or GV22 (low-current, for capacitor charging) • Earth-isolation contactor: GVL14 (latching, for passive isolation) System capacitance, battery voltage, target pre-charge time and inrush current are critical design parameters. IMB Electric blog posts cover the calculation methodology in detail. For system-level engineering support, contact our technical team.

How is the GV series mounted and in which orientations?

GV is position-independent — it can be mounted in any orientation. Depending on the model, four mounting types are available: Upright (1), Side (2), PCB M8 (4) and PCB with barrier (5). Stainless-steel hardware and inserts give years of corrosion-free service in humid, salt-laden, vibrating and heavy-duty industrial environments. PCB versions are especially compact for board-level integration.

What is the electrical life of the GV series?

Electrical life depends on load type, current, switching frequency and ambient temperature. Typical references: resistive load with up to 27 µH inductance — 100,000+ cycles; EV pre-charge (low current, high frequency) — 300,000+ cycles; industrial motor switching — 50,000-100,000 cycles. Always cross-check the datasheet curves against the actual application. Use a pre-charge circuit for capacitive loads, and keep current flow unidirectional (A1 → A2). For bidirectional duty, request a Sensata application review.

What are the lead time and pricing for the GV series?

GV is one of GIGAVAC's most-stocked families. Standard variants (GV12, GV14, GV200, GV22) are usually available immediately; specialised variants (PWM coils, latching) may have a lead time. As GIGAVAC's authorised distributor in Türkiye, IMB Electric provides stock checks, pricing and technical support. Project-based volume orders qualify for special pricing and engineering assistance.

The GIGAVAC GV series is a hermetic DC contactor family delivering economical high performance. It preserves the hermetic quality and reliability of the flagship GX, MX and HX families in a more affordable package — making it one of the highest-value high-performance choices on the market.

Alongside standard NO models, the family includes latching variants and — most notably — PWM (pulse-width modulation) coil versions that cut coil power consumption by up to 80%, ideal for continuously energised applications where energy savings and low heat matter.

GV's other key differentiator is the breadth of industrial certification: alongside UL508 and MIL-STD-810G it carries UL1604 (Class I/II Div 2, Class III) for hazardous locations, SAE J1171 and ISO8846 for marine, and IATF-16949 for automotive — covering automotive OEM supply chains, oil & gas facilities, commercial marine vessels and off-road handling equipment from a single family.
