Electronic protection devices EPD24
Ordering details
3 2CDC 051 001 S0010 The protection devices EPD24 extend the ABB product range of Modular DIN rail components by
electronic overcurrent protection modules for selective protection of 24 V DC load circuits.
EPD24-TB-101-3A This protection is achieved by a combination of active electronic current limitation in the case of a
short circuit and an overload deactivation from 1.1 x In upwards.
If a fault occurs in a load circuit, the protection device EPD24 will detect this rapidly and reliably,
disable the power output transistor and hence interrupt the current flow in the defective circuit. The
maximum possible overcurrent is always limited to 1.3…1.8 times the selected rated current. An
activation of capacitive loads up to 20,000 μF is possible, deactivation only occurring in the case of
overloads or short circuits. Selective deactivation of the defective current circuit means undefined
error states and a complete system stop are prevented.
Features
– Selective load protection, one electronic tripping characteristic.
– Active current limitation for safe connection of capacitive loads up to 20,000 μF and on
overload/short circuit.
– Current ratings 0.5 A...12 A.
– Reliable overload disconnection with 1.1 x IN
– Manual ON/OFF button
– Clear status and failure indication through LED and integrated auxiliary contact.
– Integral fail-safe element adjusted to current rating.
– Width per unit only 12.5 mm.
– Rail mounting
– Ease of wiring through busbar LINE+ and 0 V as well as signal bars.
– UL- and CSA-approvals allow international use of the devices.
