Current circuit breaker EASYB

The BLOCK electronic circuit breakers are designed for a variety of requirements in machines and devices. Available are three different tripping options. Circuit breakers with thermomagnetic, fast-tripping and current-limiting characteristics represent a cost-effective alternative to conventional circuit breakers. The wide selection of shutdown characteristics guarantee reliable tripping for any application, including at high line impedances. The requirements regarding the tripping behavior of electronic circuit breakers in machines and systems are manifold: loads with high starting and inrush currents such as drives and contactors, for instance, require different tripping characteristics to sensors and controls which react sensitively to system voltage drops. BLOCK is expanding its EasyB model range to include a new and fast tripping characteristic so that it can provide the optimum solution to the user for the relevant application in all cases. This means that safe tripping following a short circuit within 2 ms and the switching on of capacitive loads with up to 40 mF is no problem for EasyB. The new single-channel and dual-channel versions are all UL 508 and UL 2367 certified and NEC Class 2 certified from 1A to 4A. The requirements for line protection according to EN 60204-1 are also met with internal fuses individually adapted to the rated current from 1A to 10A. THE RIGHT TRIPPING CHARACTERISTIC FOR ANY APPLICATION Electronic circuit breakers are designed for the special behavior of switched mode power supplies and the DC 24 V loads they supply.
