VAMP 150 is a cost-effective motor protection with all the basic protection functions. The relay is used to protect circuit breaker controlled three phase AC motors.
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 circuits faults, internal earth faults, unbalance 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.
