G30WP Relay Selection Notes for 25kV SPST-NC High-Voltage Circuits

The G30WP relay is a high-voltage relay reference for buyers reviewing 25kV SPST-NC switching requirements. In Sorint product records, G30WP appears as a Gigavac (Sensata Technologies) high-voltage relay with vacuum dielectric, 100A current rating and screw high-voltage connection. Those fields make the model a useful starting point when a buyer needs a power relay supplier to review a specific relay request before quotation.

This technical note is written for purchasing teams handling EV support equipment, energy storage service platforms, industrial DC power systems, high-voltage test equipment and maintenance replacement programs. It is not an interchangeability approval. Final selection should be checked against the buyer's drawing, equipment requirement, qualification process and engineering review.

Core G30WP relay parameters for RFQ review

Sorint product records list the G30WP relay with an SPST-NC contact arrangement. The switching voltage is listed as 25kV DC or 60Hz, and the contact rating is listed as 100A DC or 60Hz. The relay uses vacuum dielectric and molybdenum/copper contact material. These fields should be included in the first inquiry because voltage class alone does not fully identify the relay.

The records show panel mount construction, screw high-voltage connection and turret terminal coil termination. They also list a 342 gram weight, 2 million mechanical cycles, -55 to +125 C operating temperature, 10G vibration and 30G shock. Buyers can use those values as RFQ review fields, while still confirming final acceptance criteria with their engineering team.

Coil and contact details buyers should confirm

G30WP records include non-latching coil construction. Sorint records show a 26.5 Vdc coil version under the G30WP relay name and a 12 Vdc coil version under the G30WP-12Vdc relay name. That difference should be visible in the quotation request because coil voltage affects control wiring, stocked replacement planning and comparison against an existing part label.

The SPST-NC contact form is also important. A normally closed high-voltage relay is not reviewed the same way as an SPST-NO or SPDT relay, even if the voltage class looks similar. Buyers should send the exact model number, contact form requirement and any existing approval reference so the sourcing review stays tied to the correct relay function.

Where G30WP fits in high-voltage relay sourcing

G30WP can be relevant when a project needs a 25kV normally closed relay for control, test, protection support or specialty high-voltage switching. It is a relay sourcing discussion, not the same as a high voltage DC contactor inquiry for main load switching. Separating those product groups helps the quotation process stay clear when the same purchasing list also includes DC contactors, high-voltage fuses or battery disconnect switches.

For buyers comparing G30WP with other relay references, the review should keep contact form, voltage rating, current rating, dielectric, mounting, connection style, coil voltage and timing fields visible. Sorint can help organize these points for an RFQ, but a candidate alternate should not be treated as approved until the buyer's technical team confirms it against the application.

Information to include in a G30WP relay inquiry

A cleaner G30WP relay RFQ should include the complete model reference, required quantity, destination country, target delivery date and project context. If the request is for maintenance stock, include the existing relay label or purchasing record. If it is for a new design, include the expected voltage class, current requirement, contact form, coil voltage preference and connection constraints.

Buyers can also state whether the relay is being reviewed alone or alongside other high-voltage components. When relays, contactors, fuses and disconnect switches are listed together, Sorint can separate the line items by product family and return more focused quotation questions.

FAQ

What verified rating does Sorint list for the G30WP relay?

Sorint records list G30WP with 25kV DC or 60Hz switching voltage and 100A DC or 60Hz current rating.

Is G30WP normally open or normally closed?

G30WP is listed with an SPST-NC contact arrangement, so buyers should not group it with SPST-NO relay requests without engineering review.

What coil information should be included in the RFQ?

Include whether the request is for the 26.5 Vdc G30WP relay or the 12 Vdc G30WP-12Vdc relay, along with quantity, delivery destination and application context.
