Rail-mounted Double Pole Electronic Circuit Breaker For Protection of Ungrounded Equipment

June 1, 2010 - PRLog -- E-T-A Circuit Breakers is pleased to announce the introduction of the ESS22-T rail-mounted electronic circuit breaker.  Intended for the use in ungrounded systems, the ESS22-T is the ideal solution for select types of medical equipment and subsea applications.  The ESS22-T is designed with selective disconnection and double-pole physical isolation of loads which allows the product to only disconnect the faulty load circuits in the event of an overload or short circuit.  Its rapid response to overloads or short circuits maintains a consistent control voltage for the other loads - such as PLCs, control systems and bus couplers - preventing downtime of the entire system.

Specifications
E-T-A’s ESS22-T is available in a range of current ratings from 0.5A to 10A. Short circuit currents are limited to 1.4 times the rated current and the faulty load is disconnected after approximately 100ms. Inrush peaks, from switching on capacitive loads up to 20,000 µF are tolerated, avoiding nuisance tripping. In the event of an overload, the electronic circuit breaker will disconnect at 1.1 times the rated current after 3 seconds.

The ESS22-T can be snapped easily onto industry standard rails and its slim design of 22.5 mm width x 90 mm height/depth saves space in compact control cabinets. Status indication of the connected load circuit is provided by a multicolored LED and the state of the ON/OFF switch. In the event of a failure, two physically isolated contacts provide a failure signal to the control system. The load circuit can be reset using the manual ON/OFF switch which can also be used during maintenance.

Applications:
The ESS22-T is intended for the protection of ungrounded systems.  Although this is not commonly found in many applications in the North American Market, the ESS22-T is the ideal solution for select types of medical equipment and subsea applications – where ungrounded environments exist.
