DPDT High Voltage Relays — Double-Pole Double-Throw (2 Form C)
8 models · 8-25 kVdc switching · 10-150 A continuous · Two ganged Form C contacts on one coil · Polarity reversal, multi-channel switching, transfer
The GIGAVAC DPDT family carries two mechanically ganged Form C contacts driven from a single coil (2 Form C). With the coil de-energised both poles sit on the NC contact; on energisation both transfer to NO together — a single-coil solution for multi-channel HV switching, polarity reversal and phase / redundant-feed transfer.
Hermetic / vacuum ceramic construction enables 8 kVdc up to 25 kVdc switching with 10 A to 150 A continuous current. A single coil eliminates the synchronisation problem of two separate SPDTs and halves coil count, harness mass and control electronics.
Where a latching variant of the same frame exists (e.g. G12L, G13L) the model card shows a cross-link; the configurator generates the original Sensata part-no automatically based on contact / coil / mount selections.

TECHNICAL DIFFERENTIATORS
Why DPDT Series?
Bipolar HV Transfer
A/B dual-pole source selection
Single assembly that transfers both positive and negative rails simultaneously — for redundant power.
Symmetric battery pack disconnect
In bipolar battery architectures cuts both poles simultaneously as the main disconnect.
Wide Current and Voltage Range
10 A — 150 A continuous current scale
G12, G13 (10 A) low-current signal/measurement; G53 (150 A) for railway and industrial main lines.
8 kV — 25 kV voltage range
Covers the majority of EV, railway, industrial HV and test equipment within a single family.
Latching DPDT Alternatives
G12L · G13L pulse-latching DPDT
Dual-pole versions without continuous coil power for low-power-budget systems.
Position retained on coil loss
In some safety philosophies retaining the current position is the desired behaviour.
Single-Coil Dual-Pole Synchronous Switching
Two independent Form C in one mechanism
Positive and negative lines switch in mechanical sync — no sub-millisecond mismatch.
Line-to-line short protection
Dual-pole simultaneity is guaranteed — no protection-relay misjudgement or asymmetric current risk.
