ABB 2CDE601101R2001 EPD24-TB-101-1A Electronic Protection Device
The ABB 2CDE601101R2001 is an EPD24-TB-101-1A electronic protection device designed to provide selective overcurrent protection for 24 V DC load circuits. With a rated current of 1 A, active electronic current limitation and overload disconnection from 1.1 × In, it protects individual load branches against overload and short-circuit conditions.
The EPD24-TB-101-1A detects faults in individual branches and selectively switches off the affected circuit, helping prevent a fault from interrupting other load current paths. The device supports capacitive loads up to 20,000 µF and limits the maximum possible overcurrent to approximately 1.3–1.8 times the selected rated current.
Designed as a compact DIN-rail module, the ABB 2CDE601101R2001 has a 12.5 mm width and integrated potential-free auxiliary signalling. LED indication and a manual ON/OFF function provide convenient status control and fault identification in industrial automation and control-panel applications.
