Solid State Relays Industrial, 3-Phase ZS Types RZ .... HD P., RZ .... HA P. * 3-phase Solid State Relay * Zero switching * Rated operational current: 3 x 10, 25, 40 or 55 AACrms * Rated operational voltage: Up to 690 VACrms * Control voltage 10 to 40 VDC or 20 to 265 VAC/DC * Transient overvoltage protection built-in * Prepared for overtemperature protection * Pilot duty switch available as an option * IP 10 back-of-hand protection Product Description 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- Ordering Key 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 overtemperature 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.

To perform a transient voltage clipping or suppression func- tion on the AC-load side of an RZ relay, metal oxide varistors (MOV) are normally built in. MOV's assume a low impedance state when their voltage threshold is exceeded. Carlo Gavazzi SSR's are optionally available without varistors if no transient protection is required.

Equipped with the PDS and connected to a mechanical relay, a hybrid function is achieved and it is no longer necessary to use a heatsink. The built-in timing function of the relay will ensure that the switching on and switching off is carried out by the Solid State Relay. As soon as the control voltage is applied, the power output turns on and the full voltage is applied to Operational voltage range Rated operational current Non-rep. surge current t = 20 ms Rep. overload current t = 1s I2t for fusing t=1-10 ms Off-state leakage current On-state voltage 2-124 the load. After max. 10 ms, the PDS will activate the contactor shunting the SSR in about 20 ms. As the load is already under full voltage, the contactor does not take any high inrush currents. It only bypasses the SSR. When the control voltage is removed, the pilot duty switch will first disconnect the contactor. After a delay of min. 30 ms, the load will be switched off. The power outputs will be off max. 100 ms after the input control voltage has been removed.
