Description

The ABB EPD24-TB-101 is an electronic overcurrent protection module for the load side of 24 VDC switch-mode power supplies. Combining active current limitation with overload disconnection from 1.1 × In, it protects individual 24 VDC load circuits selectively: a faulty circuit is switched off while the rest of the system keeps running, and the maximum overcurrent is always limited to 1.3–1.8 × the selected rating.

Capacitive loads up to 20,000 µF can be switched on; status is shown by LED and an integrated auxiliary contact. Width 12.5 mm per unit.
