The E-T-A ESS20-003-DC24V-2A is a solid state electronic circuit breaker designed for selective disconnection of individual loads in systems powered by DC 24V switch-mode power supplies. It responds faster to overload or short circuit conditions than the power supply itself, preventing complete system shutdown due to a single faulty load.
This circuit breaker features active current limitation, restricting the current to 1.8 times the set rated current, which allows for safe switching of capacitive and lamp loads. The current rating is selectable between 3A and 6A, providing flexibility for different application conditions. It includes a bicolour LED for status indication and a potential-free signal contact.
The ESS20 series has a compact width of 12.5 mm and can be plugged into the E-T-A power distribution socket Module 17plus, facilitating easy installation and space saving in control cabinets. It offers a push-push actuation manual ON/OFF button and provides clear status and failure indication.
Key electrical specifications include a 24 VDC operating voltage (18-32 VDC range) and a 2A current rating. The breaker type is solid state with a single pole configuration. It is approved by IEC 60934 and UL1077.
