Electronic Overcurrent Protection Circuit Breakers

Typical Applications

E-T-A electronic overcurrent protection circuit breakers are ideally suited to protect equipment components in industrial applications and supply lines which are fed by means of DC24V switch-mode power supply.


Electronic overcurrent protection prevents short-term voltage dips of switch-mode power supplies to values below 18 V both in the event of a short circuit and in the event of overload in the load circuit. At the same time the products provide selective protection or disconnection even at very unfavourable overload conditions. Other features include current-limited switch-on of loads with high input capacities without increasing the current ratings as well as failure signalling.
