Crydom / Sensata LN Solid State Relays

Crydom / Sensata LN Solid State Relays offer reliable back-to-back silicon-controlled rectifiers (SCR) switching up to 75A at 528VAC. Crydom / Sensata LN Solid State Relays couple these performance features with a trigger circuit design that allows the SSR to switch resistive loads with minimal electromagnetic noise. The series is ideal for use in commercial, residential, and medical applications. These UL-recognized and TUV-certified relays also offer superior performance in applications that require reliable switching and low-emitted noise.
