Product Overview
RCT type transformers are used indoors for a range of 0.66 kV and below rated voltage, rated frequency 50 Hz or 60 Hz, in AC circuits for current energy measurement or relay protection. The products use moulded case insulation, are small in size and light in weight, and use a mounting plate for fixed installation.
Working place: indoor. Ambient temperature -5 °C to 40 °C.
Application Scenarios
- Current measurement, monitoring and protection for electrical wiring and equipment
- Current and power measurement for electric motors, lighting, air compressors, heating and ventilation systems, air conditioning equipment and automation control systems
- Current, power and energy monitoring devices
- Relay protection devices
Technical Features
- Moulded case insulation, small size and light weight
- Mounting plate fixed installation
- Five window sizes from 25 mm to 130 mm
- Suitable for energy measurement and relay protection

Questions Buyers Ask
Is RCT suitable for outdoor installation?
No. The series is specified for indoor use, with an ambient temperature of -5 °C to 40 °C. For outdoor duty use the FSCT waterproof split core range.
How is an RCT fixed?
With a mounting plate. The body is deliberately small and light so it can be plated onto the gear rather than needing a base.
What is the largest window?
RCT-130, at φ 130 mm, covering 2000/5 A to 6000/5 A.
