Current transformer 400/5A 5VA class 1 SRC04005

Current transformer for measuring large currents.

This current transformer from Hager, model SRC04005, is a reliable device used for safely measuring high currents using meters with smaller ranges. This is particularly useful in electrical installations where it is necessary to monitor the load and provide protection against overloads and short circuits. The device provides galvanic isolation of the measuring circuit from the main current path, which increases work safety.

This transformer finds application in both industrial, commercial installations and in residential construction, where precise current measurement is required. Thanks to its design and accuracy class, it is ideal for cooperation with various types of meters and energy monitoring systems.

Characteristics and application

The SRC04005 current transformer is a through-type model, designed for mounting on a DIN rail or mounting plate. Its design allows the wire to pass through a 30 mm diameter hole, allowing current measurement without the need to interrupt the circuit. The rated primary current is 400 A, and the secondary 5 A with a power of 5 VA. Accuracy class 1 guarantees precise measurements. The FS 5 overload factor means that the transformer copes well with short-term current surges, e.g. during engine starting.

Screw connection of the secondary circuit ensures a secure and durable electrical connection. The device is also characterized by a high rated insulation voltage (3 kV), which further increases its safety of use. The use of a transformer allows to separate measuring instruments from the main circuit and place them at a safe distance, minimizing the influence of magnetic fields on their operation.
