E-T-A REX12-T electronic circuit protector

The E-T-A REX12-T electronic circuit protector has a protective element for mechanical engineering and process control. The electronic overcurrent protection combines 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. Ease of mounting and minimised wiring time help save time and money.

The single-channel circuit protector, which can be mounted side by side, uses the EM12-T supply module for installation. Both modules feature push-in technology and allow no-tool time-saving wiring. Due to its unique 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.

The product also provides selective overcurrent protection. It offers visual failure indication by means of LEDs and auxiliary contacts and thus provides ease of troubleshooting and increased machine run times.

Depending on the output current, the product disconnects after approximately three seconds in the event of an overload, and in less than 10 ms in the event of a short circuit. Thus overloading the power supply will reliably be prevented. Capacitive loads of up to 20,000 µF can be switched on without problems.

The user can operate and selectively protect even sensitive and intelligent loads. The circuit protector is available in all standard current ratings from 1–10 A. 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.
