Current transformer CTR-30 100/5 CL.0,5 004805504

Current transformer for control and measurement systems

The CTR-30 100/5 CL.0,5 current transformer is a reliable device designed to work with network parameter analyzers and automatic power factor correction (PFC) systems. Its through-hole design and precise measurements make it an ideal element in electrical installations requiring monitoring and control. Thanks to its accuracy class of 0.5, it provides reliable data, which translates into efficient energy management and system safety.

Construction and application

This transformer is characterized by a passage diameter of 30.5 mm and is adapted to measure primary currents with a value of 100 A, converting them into a secondary signal of 5 A. The rated apparent power at 1.5 VA guarantees stable operation even under load. The design of the device allows for direct mounting on a current rail or mounting plate, thanks to the included brackets. Connection terminals with a cover (IP20) ensure safety and convenience during installation and operation. Made of polycarbonate with fiberglass (flame retardancy UL 94V-0), the transformer is durable and resistant to mechanical damage.
