ABB 2CDE601101R2905 EPD24-TB-101-0.5A Electronic Protection Device
The ABB 2CDE601101R2905 is an EPD24-TB-101-0.5A electronic protection device designed to provide selective overcurrent protection for 24 V DC load circuits. With a rated current of 0.5 A and active electronic current limitation, it detects overloads and short circuits and selectively disconnects the affected branch while helping other load circuits remain operational.
Designed for installation behind 24 V DC power supplies, the EPD24-TB-101-0.5A operates across an 18–32 V DC operational voltage range and can handle capacitive loads up to 20,000 µF. Its electronic protection technology limits the maximum overcurrent to approximately 1.3–1.8 times the selected rated current.
The compact single-channel module is only 12.5 mm wide and is designed for DIN-rail mounting. A manual ON/OFF function, LED status and fault indication, integrated auxiliary contact and busbar-compatible connections make the ABB 2CDE601101R2905 suitable for compact industrial control and automation panels.

Compact 24 V DC Electronic Protection for Industrial Automation
The ABB 2CDE601101R2905 EPD24-TB-101-0.5A provides dedicated electronic protection for individual 24 V DC load circuits. When an overload or short circuit occurs, the affected branch is detected and selectively switched off, helping maintain power to unaffected circuits and simplifying fault identification.
The 12.5 mm-wide DIN-rail module is particularly suited to space-constrained control cabinets. Active current limitation, capacitive-load capability, manual switching, LED indication and an auxiliary contact provide practical protection and diagnostic functions for industrial automation equipment.
Typical Applications
- 24 V DC control circuits
- Industrial automation control panels
- PLC and I/O power protection
- Sensor and actuator supply circuits
- Industrial instrumentation
- DC control and signalling systems
- Selective protection behind 24 V DC switching power supplies
- Compact machine-control cabinets
