The E-T-A ESS20-003-DC24V-4A is an electronic circuit breaker designed for selective load protection in systems powered by DC 24V switch-mode power supplies. It responds quickly to overload or short circuit conditions, 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, allowing for the safe connection of capacitive and lamp loads. It is selectable between 3A and 6A ratings, though this specific model is rated for 4A. The device provides clear status indication via a bicolour LED and includes a manual ON/OFF push-button.
With a width of only 12.5 mm, the ESS20 is designed for space-saving installation, plugging into the E-T-A power distribution socket Module 17plus. It offers electronic trip characteristics and physical isolation in the event of a fault, ensuring reliable protection for individual loads within a DC 24V system.
Key specifications include a 4A current rating, a nominal operating voltage of 24VDC (with a range of 18-32VDC), and a solid-state breaker type. It is approved by IEC 60934 and UL1077 standards.
