E-T-A REX12-T electronic circuit protector

Click2Contact

The REX12-T electronic circuit protector from E-T-A is a protective device designed for mechanical engineering and process control. Providing electronic overcurrent protection, the REX12-T combines a high degree of flexibility with a compact design and is tailor made to the technical and economic demands of machine construction. The user does not require any additional accessories to connect the individual components electrically and mechanically, providing ease of mounting and minimised wiring time.

The single-channel REX12-T circuit protector uses the EM12-T supply module for installation. Both modules feature push-in technology and allow tool-free time-saving wiring. Due to its hinged connection mechanism, up to 16 circuit protectors can be placed and connected side by side on a symmetrical rail. No bridges, jumpers or busbars are required.

REX12-T provides selective overcurrent protection and offers visual failure indication by means of LEDs and auxiliary contacts.

Depending on the output current, the REX12-T disconnects after approximately 3 s in the event of an overload and in less than 10 ms in the event of a short circuit. Capacitive loads of up to 20,000 µF can be switched on without problems. The circuit protector is available in all standard current ratings from 1 to 10 A, and the internal fail-safe element (blade fuse), which is adapted directly to the current rating of the circuit protector, allows easy adjustment to the cable cross-section.
