ABB REJ603 (REJ603BB401NN3XE)

As a self powered feeder protection device, REJ603 does not require an external power supply. When remote areas require protection but do not have power supply, this device is an ideal choice. This device is mainly used in ring main units and secondary distribution switchgear in power distribution networks.
• Reliable protective devices suitable for distribution and secondary distribution applications
• Optional timed/inverse timed features
• Braking characteristics of transformer excitation inrush current
• Optional HMI
main advantages
• Highly suitable for low-energy trip coils
• Built in manual reset electromechanical signal board
• Take power from the USB port to avoid using the built-in battery or storing event and fault information when the CT's power supply is unavailable
• Quick debugging through selective testing of protection functions, secondary signals, and communication functions
• Fault analysis with event logs/interference records
• Self checking function
Key Features
• Cable or transformer feeders used in grounded, resistance grounded, or ungrounded systems

• Includes functions such as non directional overcurrent, grounding, overload protection, surge monitoring, remote tripping, measurement, etc 

• Low energy trip output and bistable trip output

• Interference and event records can be read from the USB interface on the front panel. It can also be read to the computer through communication. When the power is lost, it can also be powered through the USB interface 

• The self powered overcurrent and grounding protection relay • REJ603 is a commonly used component of insulated ring main units (RMUs) and compact switchgear
