Leviton Telcom CTC50-57B 5000:0.1A Split Core Ct

Product Description

The LEVITON TELCOM CTC50-57B is a split core current transformer rated at a 5000:0.1A ratio, designed for non-invasive current measurement in electrical monitoring and metering applications. Split core construction allows installation around an existing conductor without breaking the circuit, making this transformer well suited for retrofits and energy monitoring setups. Licensed electricians and instrumentation technicians install this device as part of submetering systems, power quality analyzers, and building automation panels where accurate current sensing is required without service interruption.

This current transformer is applicable to commercial and industrial electrical installations where monitoring of branch or feeder circuits is needed. Its split core design makes it a practical choice for tenant submetering, demand response monitoring, and energy management systems. The unit ships as a single piece per the supplier unit of measure.

Key Features

• 5000:0.1A current ratio for high-resolution current sensing on large conductors
• Split core construction enables installation on energized conductors without circuit interruption
• Single-unit packaging supports individual circuit monitoring deployments
• Compact form factor suitable for panel and enclosure mounting

Compatibility

Designed as an OEM-style replacement or addition for split core current transformer applications in commercial and industrial submetering and energy monitoring systems.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements for instrument transformers and metering equipment. Always verify that conductor insulation is intact before clamping the split core around the conductor. Secure the core halves fully closed before energizing to ensure accurate readings and safe operation. Do not exceed the rated primary current for this transformer.
