Littelfuse Latching Relay

The SD series relay gives the option of an all-vehicle remote disconnect switch. It is ideally suited for applications with continuous high-current, large engine starting needs or high ambient temperatures. It utilises small control cables for operation eliminating the need to run heavy, expensive copper cables to the operator.

It is SAE J1171 ignition protected and ISO 8846 rated for instillation in a battery box or on vehicles carrying hazardous loads.
