Current transformer 413 300/5 5VA Class 1 SRI03005

Current transformer for busbar systems

The 413 300/5 5VA Class 1 current transformer is a component used for precise current measurement in electrical circuits. It is particularly useful in busbar systems where it is necessary to monitor the load and ensure safety. The device allows the conversion of a high primary current into a safe and measurable secondary current, which can be used by meters, protective relays or automation systems.

Construction and application

Through-type transformer with a passage diameter of 28 mm, designed to work with primary currents up to 300A. The rated secondary current is 5A, and the apparent power is 5VA. The construction with touch protection increases safety, and the snap-on mounting allows for quick assembly and disassembly. Designed for installation inside buildings, in electrical switchboards and control cabinets.
