G15LSP Relay Selection Notes for 15kV SPDT Latching High-Voltage Circuits

The G15LSP relay gives buyers a specific latching high-voltage relay option when a project calls for SPDT switching, compact high-isolation control and a 15kV class requirement. Sorint product data lists the G15LSP relay as a Gigavac product from Sensata Technologies with a 15kV SPDT bistable description, making it relevant for sourcing reviews in test equipment, battery systems, industrial control panels and other high-voltage circuits.

This technical note is written for procurement and engineering teams preparing a quotation request. It does not replace the buyer's design approval process, but it can help organize the model data that should be checked before a purchasing decision is made.

Start with the switching form and voltage class

The local Sorint product data identifies the G15LSP relay with an SPDT contact arrangement and a switching voltage reference of 15kV DC or 60Hz. For buyers comparing high-voltage relay options, that means the request should clearly state whether the circuit needs single-pole double-throw switching rather than SPST, DPDT or another relay form.

The same record lists a 12 A contact rating and molybdenum/tungsten contact material. These fields help buyers separate a direct G15LSP model request from a broader search for high-voltage relay alternatives. If a buyer is replacing an existing part, the RFQ should include the exact model number, label photo if available, required quantity and destination country.

Latching behavior changes the RFQ details

G15LSP is listed in the latching high-voltage relay series, with latching coil type in the product fields. Latching relay requests should make the expected coil details clear because buyers may be comparing similar model names with different coil voltages or termination preferences. Sorint data lists the G15LSP coil voltage as 26.5VDC and the coil termination as turret terminal.

For procurement teams, this is a useful reminder that a relay quotation should not stop at the voltage class. A complete request should include contact form, coil voltage, coil type, termination style, mounting type and expected purchasing schedule. These details reduce back-and-forth when the sourcing review involves several high-voltage relay families.

Mounting and connection fields help confirm fit

The G15LSP product record lists panel mount as the mounting type, solder pot as the termination style and solder pot as the high-voltage connection. The same data lists an inert gas dielectric, 84 gram weight, 15 ms operate time, 9 ms release time, 10G vibration and 50G shock references.

These fields are useful for preparing an RFQ because they describe the exact model context buyers should confirm against their approved drawing, specification sheet or maintenance requirement. Sorint can use these inputs to review the requested model and related high-voltage relay options, but final suitability should remain with the buyer's engineering approval.

Where G15LSP fits in high-voltage relay sourcing

Buyers often review high-voltage relays alongside DC contactors, battery disconnect switches and high-voltage fuses when a project includes switching, isolation and protection requirements. The G15LSP relay belongs in the relay portion of that sourcing package, especially where SPDT latching behavior and 15kV class selection are part of the discussion.

When preparing a request, buyers can start from Sorint's power relays category or the high-voltage relays range. If the inquiry also includes main DC switching or protection components, related categories such as power contactors and high-voltage fuses can be included in the same RFQ.

FAQ

What is the key selection point for a G15LSP relay request?

The request should confirm the G15LSP model, SPDT contact form, 15kV voltage class, latching coil type, coil voltage, termination style, mounting type and quantity.

Is G15LSP listed as a latching relay?

Yes. Sorint product data lists G15LSP under latching high-voltage relays and identifies the coil type as latching.

What coil voltage appears in the Sorint product data?

The G15LSP relay record lists 26.5VDC coil voltage with turret terminal coil termination.

Can buyers include G15LSP with other high-voltage components in one RFQ?

Yes. Buyers can include G15LSP with DC contactors, battery disconnect switches or high-voltage fuses when the inquiry separates each line item and includes quantities, application background and delivery needs.
