The ABB REJ603 REJ603BB401NN3XE is a self-powered numerical feeder protection relay that is primarily designed for the selective short-circuit and earth fault protection of feeders in secondary distribution networks and for protection of transformers in utilities and industries. It is a CT-powered protection relay and is based on a microprocessor environment. The relay is used in combination with a special ring type current transformer.
Here are some of the key technical specifications of the ABB REJ603 REJ603BB401NN3XE:
Rated voltage: 110/120 VAC, 220/240 VAC
Rated current: 1A (external)
Number of protection elements: 3
Type of protection elements: overcurrent, earth fault, thermal overload
Communication protocols: Modbus, IEC 61850
Dimensions: 144 mm x 88.5 mm x 118 mm (W x H x D)
Weight: 1.5 kg
Here are some of the key features of the ABB REJ603 REJ603BB401NN3XE:
Self-powered: The relay receives power from the main current transformers, so there is no need for an external power supply.
Numerical: The relay is based on a microprocessor environment, which provides a high level of accuracy and flexibility.
Selective: The relay is designed to provide selective protection of feeders in secondary distribution networks.
Immune to magnetizing inrush: The relay employs a proven technique of blocking based on measured value of second harmonic content to make the protection immune to magnetizing inrush.
Modbus and IEC 61850 communication: The relay supports Modbus and IEC 61850 communication protocols, which allows it to be integrated into a wide range of SCADA systems.
