Compact Zero Speed Switch
SMARTsaa offers compact Zero Speed Switch housed in sensor housing itself. No need of separate control unit. The sensor and control circuit is housed in sensor housing (IP 67). It is simple, cost effective and easily mountable at site.
In case of under speed â zero speed application built-in initial by-pass time delay is provided to allow the rotating machinery to attend the desired speed. If after this set time the motor does not attend the set speed, the load relay is de-energized and the switch resets automatically when the desired speed is attained.
