Carlo Gavazzi Solid State Relay 3-Phase Zero-Cross RZ4055HDP0

Carlo Gavazzi Solid State Relay 3-Phase Zero-Cross with LED, Control: 10-40VDC, Operational: 400VAC, 3x55A.

A Solid State Relay family designed to switch various loads such as heating elements, motors and transformers. The relay is capable of switching high voltages up to 690 VACrms. Technique for higher reliability and load cycle capability three alternistor chips are soldered directly on to the direct copper bonded (DCB) substrate. AC or DC-controlled versions are available. Built-in LED status indication for applied control voltage. Other features include overvoltage protection via the varistors and the possibility of installing a thermostat for over temperature protection. When equipped with a pilot duty switch and connected to a mechanical relay a hybrid function is achieved, and it is no longer necessary to use a heatsink.
