Datasheet
**REX12 Electronic Circuit Protector** ## **Description** Lo 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 20,000 µF 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. ## **Features** Lo > l Combination of supply modules, overcurrent protection and power distribution - l Single and double channel selective load protection by means of electronic trip curve ## **Benefits** Lo - l Saves cost – no further accessories required l Saves 50 % time through innovative and flexible mounting and connection technology - l Saves space – with a width of only 12,5 mm per channel - l Provides flexibility through ease of mounting, disassembly and modular design - l No accessories required for connecting the components l Width per channel only 12.5 mm (1-channel) or 6.25 mm (2-channel) - l Fixed current ratings from 1 A to 10 A - l Integral fail-safe element, adjusted to current rating - l Switching capacitive loads up to 20,000 µF - l Manual ON/OFF/reset momentary switch - l Clear status indication by means of LED and signal contact Si - l Connection via push-in terminals including orange press release buttons ## **Preferred types – a short explanation. For more details on all configurations please see ordering number code on page 3** Preferred types are E-T-A products most frequently used by our customers. We manufacture our preferred types in substantial quantities. At the same time our preferred types are supplied at shorter lead times than non-standard versions. ## **Preferred types** |**Preferred types**||||||||| |---|---|---|---|---|---|---|---|---|

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
