Single circuit protector for load groups

The new 16A version ESX10-TB can protect groups of loads with a total current of up to 16A using a single circuit protector. Designed to reduce downtime and danger to personnel on production lines, it is ready for direct rail mounting, singly or in groups. Single or group signalisation is quickly attainable.

The ESX10 Electronic Circuit Breakers, available as plug-in or rail mounting versions, provide electronic overcurrent protection according to UL2367 for 24V DC control circuits and load currents from 05A to 16A: in the event of overload or a short circuit, the faulty load will be disconnected electronically by means of a mosfet in the output circuit of the protector. It ensures selective disconnection of 24V DC switch-mode power supply (SMPS) loads while optimally matching the application requirements.

The E-T-A ESX10 provides active current limitation from 1.3 to 1.8 times its rated current. This allows capacitive loads of up to 75,000μF or lamp loads to be switched on without affecting other loads on the power supply. At the same time, this electronic active current limitation responds quickly to overload or short circuit conditions: the ESX10 will shutdown electronically a single faulty output, while allowing all other load circuits connected to the same SMPS to continue working as normal.

The E-T-A ESX10-TB is just 12.5mm wide and can be mounted directly on a DIN/EN rail. Status indication is provided by a multicolour LED plus an integral short-circuit proof status output or potential-free signal contact. In the event of an overload or short circuit, the load circuit may be re-activated via a remote electronic re-set signal, a remote control signal or by a manual ON/OFF button. The ON/OFF button also allows manual disconnection when starting up a system or during maintenance. Some versions are available with ATEX approval. Drives & Controls Stand D654
