Current transformer CTR-30 75/5 CL.1 004805502

Current transformer for control and measurement systems

The CTR-30 75/5 CL.1 current transformer is a reliable and proven device used in control and measurement systems, network parameter analyzers, and automatic power factor correction (PFC) systems. Its through-hole design and precise parameters make it a key component in electrical installations requiring accurate current measurement.

Construction and application

This transformer, with a 30.5 mm diameter aperture, is designed to work with primary currents up to 75A, converting them into a safe and measurable secondary signal of 5A. The rated secondary apparent power is 1.5 VA, ensuring stable operation under various conditions. This is particularly important in applications requiring high measurement accuracy. Accuracy class 1 guarantees reading accuracy, and a system voltage of up to 720V allows for a wide range of applications.

Mounting and additional functions

The CTR-30 75/5 CL.1 offers flexible mounting – it can be mounted directly on the busbar or mounting plate using the included brackets. The kit also includes cable and busbar brackets with a clamping screw, making installation easier and ensuring a secure connection. The housing made of polycarbonate with fiberglass (flame retardancy UL 94V-0) ensures durability and safety of use even in harsh environmental conditions. Additionally, optional adapters for mounting on a TH rail are available. Connection terminals with a cover (IP20) increase safety and minimize the risk of accidental contact.
