The MP0CAE3 is a surge suppressor diode for contactor coils. Designed to reduce the maximum overvoltage peak value and to limit or even completely eliminate the high pre-damping voltage frequencies for a rated control circuit voltage between 6 ... 240 V. The surge suppressor is simply plugged onto the front of all MC1, MC2 and MCR DC operated variants.
This SMK3.0 mounting kits allow to mount EIU32.0, PNU32.0, DNP31.0, MRP31.0, PDR31.0 and PDP32.0. The SMK3.0 mounting kit itself can be placed outside of the drawers, for example in the cable compartment.
