The 3RV1 MSP’s have three main contact elements. In order to achieve maximum flexibility, auxiliary switches, signalling switches, auxiliary releases and isolator modules can be supplied separately. These components can be fitted as required on the switches without using tools.
One of the three auxiliary switches can be mounted laterally for each MSP. The contacts of the auxiliary switch close and open together with the main contacts of the MSP. The overall width of the lateral auxiliary switch with 2 contacts is 9 mm.
