Which applications is the SPDT series suitable for?

The right SPDT series use case depends on switching voltage, continuous current, inrush current, coil supply, mounting orientation and environmental conditions. For critical projects, verify the model-table datasheet ratings against your actual load profile.

What should I check first when selecting a SPDT model?

Start with system voltage and continuous current; then check break capacity, inrush rating, coil voltage, auxiliary contact needs and datasheet temperature limits. The configurator builds the order code according to the manufacturer code structure.

Do datasheet ratings and configurator codes refer to the same product?

Yes. The series table shows technical limits; the configurator turns coil, contact, terminal and option selections within the same model family into an order code. For quotation, send both the generated code and your application note.

Do you provide technical support and cross-reference checks for this series?

Yes. Share your existing part number, operating voltage, load type and environmental conditions, and we can review technically suitable alternatives within the same series or adjacent product families.

What information should I send for a quotation?

The generated part number, quantity, target delivery date, application type, system voltage/current and any datasheet revision are enough. The RFQ cart helps collect these details in one request.

Will this information appear the same after publishing?

Yes. The FAQ and related-insights blocks are part of the application code and appear with the same design on the published site.

GLVAC SPDT HV Relay

3.5 kV – 35 kV Single Pole Double Throw (SPDT) high-voltage relay family

GLVAC SPDT (Single Pole Double Throw) HV Relays are designed for high-voltage applications requiring precise circuit routing. The SPDT architecture allows a single contact to switch between 2 different circuits — critical in RF antenna switching, test equipment measurement routing, and redundant power supply applications.

20 different models offer working voltage from 3.5 kV to 35 kV. Available in vacuum-insulated (GL series: GL41C, GL45C, GL43C, GL81C, GL2, GL8, GL9, GL10, GL15, GL52), reed (GLH series: GLH1, GLH2, GLH3, GLH4, GLH5), and latching (G series: G2L, G8L, G15L, G60L) technology options.

Typical applications: RF antenna switching (antenna selection), redundant power supply (A/B backup line), test equipment measurement routing, telecommunications switch matrix, satellite communication signal routing, and aerospace system routing.
