50058786-003 Current Sensor

Description:

The Honeywell / E-Mon 50058786-003 Current Sensor is a split-core current transformer used in electrical monitoring systems to measure AC current without interrupting the circuit. It is commonly installed in energy management systems, industrial power monitoring panels, building automation systems, and metering equipment where accurate current sensing is required. Maintenance teams, electricians, and OEMs use this sensor for energy audits, load monitoring, system diagnostics, and replacement of failed current transformers.

Applications:

The 50058786-003 Current Sensor is designed for non-invasive current measurement in electrical distribution systems. It is commonly used in commercial buildings, industrial plants, HVAC systems, and energy management platforms to monitor power consumption, detect overload conditions, and support sub-metering systems. Split-core construction allows installation around existing conductors without disconnecting wiring, making it suitable for retrofit and maintenance applications.
