Built with safety in mind, MSEL SSR Isolators have been designed with the sole purpose of living in a motorsport environment. Utilizing solid state switching components, the Master Relay has excellent temperature resistance, as well as an aluminum enclosure that is lightweight and robust in even the harshest motorsport environment.

Both race car battery isolators are identical and offer the same functionality aside from the connection type. The Club Level isolator includes a flying lead harness to be terminated to the connector of your choosing. The Professional Level isolator utilizes a Souriau connection (mating connector available in the dropdown).
