Protection and safety
Electronic Protection Devices for use behind 24 V DC Switch Mode Power Supplies

The protection devices EPD24 extend the ABB product range of modular DIN rail compo-
nents by electronic overcurrent protection modules for selective protection of 24V DC load
circuits.
5
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 reli-
EPD24 ably, disable the power output transistor and hence interrupt the current flow in the defec-
tive circuit. The maximum possible overcurrent is always limited to 1.5…1.8 times the se-
lected 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 trip characteristics.
• 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 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.
