With Power Contactor Enabling Circuits Devices of the 3RA71 series have a number of electronic evaluation units, each of which is equipped and electrically connected to two redundantly switching power contactors (utilization category AC-1 and AC-3). The devices can be ordered as certified units. For small machine tools and processing machines with just one motor, e.g. for milling, the safe load feeder combines the function of a fuseless or fused motor starter with that of an emergency stop shutdown. The advantages at a glance - Can be used up to category 4 - Stop category 0+1 possible - Expandable - Connection of sensors with contacts and electronic sensors - Short-circuit proof to 50 kA - Integrated overload and short-circuit protection - AC-1 and AC-3 switching capacity - Outgoing feeders up to 11 kW, type of co-ordination 2 - Fused or fuseless design - Cascading and functional switching possible, e.g. via PLC
