Type: REX12-T

Description

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

The compact and flexible all-in-one solution REX consists of several perfectly matched components. It comprises the EM12-T supply module for the plus and minus potential via a single or double channel REX12-T electronic circuit protector which can be mounted side by side in any number and the PM12-T potential extension module for plus and minus multiplication.

Connection of the only 12.5 mm wide modules is exclusively with push-in terminals which 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 built-in connector system - no further accessories required. The circuit protector REX12-T offers selective overcurrent protection by responding to short circuit or overload faster than the switch 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.

Besides the UL508listed approval and NEC Class2, the REX12-T also meets the requirements of cable protection to EN60204-1.
