Contactor relays are switching devices for control and auxiliary circuits and are used for controlling, signaling and locking switching devices and switchgear. Naturally, SIRIUS 3RH2 contactor relays come with standard-compliant connection designations and a connection system that saves both time and installation overhead. This makes them particularly suitable for practical applications. The 3RH2122-1AP00 contactor relays and size S00 motor contactors are the same size and have an identical design – a significant advantage, particularly with regard to the accessories.
They are designed for AC or DC operation and are available with screw or spring-loaded terminals. The basic version of the contactor relays is a 4 pole design which can be extended up to eight poles by means of snap-on auxiliary switches.
