Why Choose the ABB CM-CT 50/1 Current Transformer?
The ABB CM-CT 50/1 is a reliable plug-in current transformer designed for current measurement and monitoring in industrial electrical systems. Supplied under ABB order code 1SVR450116R1000, it converts a rated primary current of 50 A to a secondary current of 1 A, providing a convenient reduced-current signal for compatible measuring and monitoring equipment.
As part of the ABB CM-CT current transformer range, the CM-CT 50/1 provides a rated burden of 1 VA with accuracy class 1. Its solid-core, through-conductor design allows the primary conductor or busbar to pass through the transformer aperture, providing galvanically isolated current transformation without requiring a conventional primary winding connection.
The CM-CT 50/1 has compact overall dimensions of approximately 78.5 × 61 × 48 mm and a net weight of approximately 0.31 kg. It is supplied with a foot angle, insulating protective cap and bar fastening screws, while an optional snap-on accessory is available for DIN-rail mounting.

Reliable Current Transformation for Measuring and Monitoring
Current transformers reduce relatively high primary currents to standardised secondary currents that can be safely and conveniently processed by compatible measuring, monitoring and control equipment. With its 50 A to 1 A transformation ratio, the ABB CM-CT 50/1 provides a proportional secondary signal while electrically isolating the measuring circuit from the primary conductor.
The CM-CT range is suitable for industrial switchboards, control cabinets and machinery where current measurement is required for monitoring, metering or protective functions. The CM-CT 50/1 can be panel mounted, while the optional CM-CT A snap-on fastener provides an alternative solution for DIN-rail installation.
Typical Applications
- Industrial current measurement and monitoring.
- Electrical control panels and switchboards.
- Measuring and monitoring relay circuits.
- Industrial machinery and automation systems.
- Load and current monitoring applications.
- Electrical distribution and control equipment.
