Industrial 50058786-003 Current Sensor Split Core Transformer

The Honeywell / E-Mon 50058786-003 Current Sensor is a split-core current transformer that lets you measure AC current non-invasively without disconnecting the circuit. It clamps around existing conductors in energy management systems, commercial or industrial panels, HVAC controls, and metering equipment, making retrofit and maintenance straightforward. Designed for indoor industrial/commercial environments and 50/60 Hz operation, this hinged split-core CT delivers a low-voltage secondary signal to compatible meters or monitoring equipment, with an approximate current range of ~200 A (variant dependent). The installation is non-intrusive, using the clamp mechanism for panel or conductor mounting. It is specified for use with E-Mon / Honeywell energy meters and monitoring platforms to support energy audits, load monitoring, system diagnostics, and sub-metering. Common replacements include the E-Mon D-Mon split-core CT series (matching amperage range variants), Veris split-core CTs, and CR Magnetics split-core CT series.
