G25SP Relay Selection Notes for 25kV SPDT High-Voltage Circuits

Selection notes for G25SP relay RFQs covering 25kV SPDT contact form, 18A rating, vacuum dielectric and sourcing details.
The G25SP relay is a high-voltage relay reference for buyers who need a 25kV SPDT switching option rather than a main DC contactor. In Sorint product data, the G25SP relay is listed as a Gigavac (Sensata Technologies) model in the SPDT high-voltage relay group. The verified fields identify 25kV DC or 60Hz switching voltage, 18A DC or 60Hz current rating, vacuum dielectric and a non-latching coil type.
Those details make the model useful for quotation discussions where the buyer already has a project drawing, approved vendor list or previous relay reference. The notes below summarize the fields Sorint can use to start a sourcing review. Final selection should still be checked against the buyer's application requirements and manufacturer documentation.
Core G25SP relay parameters for quotation review
The G25SP relay is listed with an SPDT contact arrangement and molybdenum/tungsten contact material. Its dielectric is listed as vacuum, and the voltage rating is 25kV DC or 60Hz. The contact rating is listed as 18A DC or 60Hz. These fields should be visible in the first inquiry because voltage class alone is not enough to identify the correct high-voltage relay.
For a power relay supplier review, buyers should send the complete model reference, quantity, target schedule and application background. If the request is part of a replacement review, the existing drawing or approved part list can help confirm whether the discussion should stay with G25SP or compare another SPDT high-voltage relay option.
Mounting, termination and coil details to confirm
Sorint data lists panel mount as the mounting type and solder pot as the high-voltage connection for G25SP. The coil is listed as non-latching with 26.5 Vdc coil voltage and turret terminal coil termination. These connection details are often just as important as voltage and current values because they affect how the relay fits into an existing assembly.
The listed operate time is 15 ms, and the listed release time is 15 ms. Mechanical cycles are listed as 1 million. Operating temperature is listed as -55 to +125 C, with vibration listed as 10G and shock listed as 20G. Buyers can include these parameters when comparing relay options, but the project engineer should confirm the final acceptance criteria.
Where G25SP fits in high-voltage relay sourcing
G25SP is most relevant when the purchasing request names a 25kV SPDT high-voltage relay for control, test, charging support, energy storage support equipment or industrial DC power systems. It is not the same conversation as a high voltage DC contactor RFQ, even though both product groups appear in high-voltage power control projects.
When the application needs SPDT contact form and a 25kV rating, identifying G25SP early can reduce unnecessary back-and-forth. When the application instead needs a different contact form, latching function, screw connection, lower voltage class or main current switching device, Sorint can review the broader high-voltage relay and DC power relay request separately.
Information to send with a G25SP relay inquiry
A clear inquiry should include G25SP relay as the requested model, the required quantity, destination country, target delivery timing and whether the order supports a new build, maintenance stock or approved-source review. If the buyer has a preferred coil voltage, connection requirement or acceptance document, those details should be shared at the start.
Buyers may also ask Sorint to review related high-voltage relay families when availability, schedule or purchasing policy requires more than one option. In that case, the comparison should not assume interchangeability. Contact arrangement, dielectric, mounting, high-voltage connection, coil details, operating temperature and timing fields all need engineering confirmation before an alternative is accepted.
FAQ for G25SP relay buyers
What verified rating does Sorint list for the G25SP relay?
Sorint product data lists the G25SP relay with 25kV DC or 60Hz switching voltage and 18A DC or 60Hz contact rating.
Is the G25SP relay a latching relay?
No. The available product data lists G25SP as a non-latching relay with 26.5 Vdc coil voltage and turret terminal coil termination.
What connection information should be included in an RFQ?
The inquiry should include the model number, contact form, mounting type, high-voltage connection, coil voltage, required quantity, target delivery schedule and any project-specific acceptance requirements.
