G12SP Relay Selection Notes for 8kV DPDT High-Voltage Circuits

The G12SP relay is a high-voltage relay reference that buyers often review when a project needs an 8kV DPDT contact arrangement in a compact panel-mounted package. Sorint product data lists the G12SP relay family as Gigavac (Sensata Technologies) high-voltage relays with 8kV DC or 60Hz voltage rating and 10A current rating. Those verified fields make the model useful for RFQs where the buyer is comparing high-voltage relay options for controlled switching, test equipment, charging support equipment, energy storage systems or industrial power control assemblies.

This note focuses on the G12SP family fields that should be visible in a quotation request. It does not replace a project drawing or manufacturer documentation, but it helps procurement and engineering teams send a clearer starting point before availability, pricing, approved alternatives and delivery timing are reviewed.

Core G12SP relay parameters for RFQ review

Sorint product data lists the G12SP relay with a DPDT contact arrangement, molybdenum/tungsten contact material and vacuum dielectric. The listed mounting style is panel mount, with solder pot high-voltage connection and turret terminal coil termination. These details matter because many high-voltage relay inquiries begin with only a voltage class, while sourcing review depends on contact form, connection style, mounting expectation and the specific coil requirement.

For rating references, the G12SP relay family is listed with 8kV DC or 60Hz switching voltage and 10A current. Buyers comparing a power relay supplier or high voltage relay supplier should include the full model reference, target quantity, application background and any approved replacement list. That information keeps the discussion centered on the relay family instead of moving into unrelated DC contactor, battery disconnect switch or high-voltage fuse options.

Coil options and connection details to confirm

The G12SP family appears in Sorint data with non-latching coil type across several coil voltage references, including 12 Vdc, 26.5 Vdc and 115 Vdc variants. Because coil voltage changes the exact model conversation, buyers should avoid sending only the short family name when the purchase record identifies a voltage suffix. The coil voltage, contact arrangement and termination style should travel together in the first RFQ message.

Connection details are equally important. The listed high-voltage connection is solder pot, and the listed coil termination is turret terminal. The product data also includes 1 million mechanical cycles, -55 to +125 C operating temperature, 15 ms operate time, 9 ms release time, 10G vibration and 30G shock. These values are useful for comparison and documentation review, while final use should follow the buyer's approved engineering checks.

Where G12SP relay sourcing requests commonly fit

G12SP relay requests usually fit buyer conversations around high-voltage control circuits rather than main traction-current switching. The family can be relevant to test systems, charging equipment, energy storage support equipment, industrial power systems and other applications where an 8kV DPDT high-voltage relay is named in the approved bill of materials or replacement record.

When an inquiry is described only as a DC power relay need, the scope can become too broad. A power relay supplier may need to separate high-voltage relay references from high-voltage DC contactors, battery disconnect switches and fuse protection components. Naming G12SP, the exact coil voltage and the expected quantity helps Sorint review the request faster and respond with a more focused sourcing discussion.

Information to send with a G12SP relay inquiry

A practical G12SP inquiry should include the model number, coil voltage, quantity, required schedule, destination country and whether the order supports a new build, service stock or approved replacement review. If a buyer has a previous purchase record, drawing reference or approved vendor list, sharing the non-confidential portion can reduce follow-up before quotation.

Buyers should also state whether nearby relay models are acceptable for review. Some projects require the exact G12SP reference, while others may compare latching versions, different contact forms or other voltage classes. Keeping the G12SP parameters visible from the first message helps the RFQ move from broad search language into a concrete high-voltage relay sourcing review.
