- E-T-A Circuit Breakers
August 9, 2018 –E-T-A Circuit Breakers announced its REX12D-T, the latest addition to the REX Electronic Protection System that includes supply modules, overcurrent protection devices, and power distribution modules. This modular architecture allows designers to customize the REX sytem to specifically meet the system requirements. The REX12D-T circuit protector, in combination with the EM12D-TMB supply module that communicates via Modbus-RTU protocol, is intended for those looking to incorporate condition monitoring and predictive maintenance into their systems.
The REX12D-T is available in a single or double channel version. The single-channel version is available in 8A and 10A fixed current ratings. The double-channel version, which offers double load protection in a 12.5mm wide device (or 6.25mm per channel), is available in fixed current rating combinations of 1 A/1 A, 2 A/2 A, 3 A/3 A, 4 A/4 A, 6 A/6 A. Loads, with a total rating up to 40A, can be protected by circuit breakers mounted side-by-side on a DIN Rail that are connected with a hinged connector arm.
The REX12D-T status indication, both on the device itself and also on a system HMI via Modbus-RTU communication protocol, allows technicians to constantly monitor the status of the REX system and identify faulty loads that need attention. Faulty circuits will selectively be disconnected after approx. 3 seconds and after less than 10 milliseconds in the event of a short circuit.
The REX12D-T is UL 2367 and UL 1310 NEC Class2 approved, and cULus 508 listed.
