Sensors, Monitors & Protective Relays
- Use internal electronic circuits to detect, monitor and/or sense current, voltage, frequency, phase and/or power
- Open or close a circuit when certain pre-set conditions exist
- Hermetic or gasket seal models designed for demanding conditions
- Panel or DIN-rail mounting for industrial environments
- Many are adjustable by the user, and some are highly customized for a given application.
