Autonics SRH3-1275 Three-Phase Solid State Relay, Panel Mount SSR

The Autonics SRH3-1275 is a three-phase solid state relay from the SRH3 series, designed for reliable switching of AC loads in industrial automation systems. It features an integrated heatsink, 3-phase control, 4–30 VDC input voltage, 24–240 VAC load voltage, and a rated load current of 75 A. This SSR is suitable for panel mounting and is commonly used for heater control, motor-related switching applications, and other high-current industrial load control systems.

Features:

Three-phase solid state relay with 3-pole output
Rated load current: 75 A
Load voltage range: 24–240 VAC
Input voltage: 4–30 VDC
Zero-cross turn-on output for reduced electrical noise
Integrated heatsink type for improved heat dissipation
High dielectric strength: 4,000 VAC
Screw terminal connection for secure wiring
Designed for industrial AC load switching
Suitable for panel mounting; some listings also reference DIN rail compatibility, but Autonics notes that DIN rail mounting is not available for 50 A and 75 A load current models.
