Rex12-T Electronic Circuit Breakers

E-T-A Circuit Breakers Rex12-T Electronic Circuit Breakers are compact, flexible, all-in-one solutions with several perfectly matched components that provide overcurrent protection for 24V_DC systems. The circuit breakers pair with the EM12-T supply module for side-by-side mounting and require no special accessories to connect. This connection technology, plus a press release button, reduces installation time by 50% and offers added flexibility for future system upgrades. The push-in circuit breakers are available in single- or double-channel configurations, each 12.5mm wide. The Rex12-T circuit breakers feature a 24V_DC voltage rating and include models with current ratings from 1A to 10A. The REX12-T electronic circuit protection solution is ideal for machine and panel builders and features UL 2367, UL508, and UL 60947 approvals.
