3RH2131-1AP00 SIRIUS 3RH21 CONTACTOR RELAY, 1 NC+3 NO, 230 V AC

Contactors are switching devices for control and auxiliary circuits and are used, among other things, to control, signal and interlock switchgear and switchgear. The SIRIUS 3RH2 contactor relays naturally have standard-compliant connection designations and a time-saving and cost-saving connection technology. This means that they are particularly suited to the requirements of practice. The 3RH2 contactor relays and the size S00 motor contactors are of the same size and have the same design, a major advantage, especially with regard to accessories.

They are designed for AC or DC operation and are available with screw or spring-loaded technology. The basic version of the contactor relays is 4-pole and can be extended to eight poles by means of snap-on auxiliary switches.
