Vamp Feeder, Motor Manager Ready for Delivery

The motor protection relay type VAMP 150 is an ideal protection relay for circuit breaker-controlled, three-phase asynchronous motors. The relay is used for internal short-circuit faults, internal earth faults, unbalanced single phasing, incorrect phase sequence, overload protection and too frequent starting. The relay includes also an undercurrent function to protect the load driven by the motor e.g. a pump.

The relay is further provided with a mA output for measuring the load current. As an option, the relay can be provided with an arc detection system, which in combination with the extremely fast overcurrent stage, forms a fast arc protection function.
