Typ REX12-T von E-T-A: Der Sicherungsautomat REX12-T bietet selektiven Überstomschutz.


The electronic circuit protector REX12 consists of the supply module EM12-T and the single-channel or double-channel electronic circuit protector REX12-T for side-by-side mounting.

The only 12.5 mm wide modules feature push-in technology and allow no-tool time-saving wiring.


Depending on the requirement, up to 16 circuit protectors can be placed on the symmetrical rail and are electrically connected by means of a flap-hinged mechanism - no further accessories required. The circuit protector REX12-T offers selective overcurrent protection by responding to short circuit or overload faster than the switched mode power supply.

Capacitive loads of up to 20,000µF can be switched on without problems. The circuit protectors are available in all standard current ratings from 1 A to 10 A. Ease of adjustment to cable cross section is ensured by the internal fail-safe element (blade fuse) which is directly adjusted to the current rating of the circuit protector.
