SRH2/3 Series

The SRH2/3 series three-phase solid state relays are integrated heatsink types, which are removable. The solid state relays can control 2-phase or 3-phase loads and feature two mounting hole types for compatibility with various types of heatsinks. The series also features alarm output for safe operation, and are also available in 24 VAC low voltage models. Select models feature high dielectric strength of up to 4000 VAC and integrated heatsink models can be mounted on to both DIN rails and panels.
