ABSTRACT:
A current sensing module is provided for contactors and similar switch gear. The current sensing module is packaged so as to be capable of mounting on a line or a load side of a contactor. The current sensing module may be eliminated where current signals are not needed, but can be added to the package where monitoring and control functions may benefit from sensed current signals on either or both sides of a contactor. The current sensing module may be configured as a single or multiple-phase device, and may output either analog or digital signals to local devices or to networked devices.
