ABB REJ513 Overcurrent Protection Relay
ABB REJ513 Overcurrent Protection Relay Supplier and Exporter in India
ABB REJ513 Legacy Spare and Replacement Enquiries
ABB REJ513 is a numerical overcurrent relay used for short-circuit and overcurrent protection of medium-voltage feeders and busbars. For price and availability, send the complete ABB order code, relay nameplate, quantity and destination country.
Description
ARP IMPEX supplies and exports ABB REJ513 overcurrent protection relays for medium-voltage switchgear, substations and industrial power-distribution systems.
REJ513 is a dedicated three-phase overcurrent relay. It continuously measures the phase currents through conventional current transformers and operates when the current exceeds the selected protection settings. The relay can trip the circuit breaker, provide alarm signals and record fault information when an overcurrent or short-circuit condition is detected.
The relay has two protection stages. The low-set overcurrent stage can operate with definite-time or IDMT characteristics, while the high-set stage can be set for instantaneous or definite-time operation. ABB also notes that the relay can be used for two-stage load-shedding applications when the high-set stage is adjusted within the lower part of its setting range.
REJ513 is mainly associated with feeder and busbar protection, but ABB also documents its use wherever single-, two- or three-phase overcurrent protection is required.
For ABB REJ513 price, legacy spare availability or replacement enquiries, send us the complete part number and a clear photograph of the existing relay nameplate.

Features
- Three-phase overcurrent protection
- Short-circuit protection
- Low-set overcurrent stage
- High-set overcurrent stage
- IDMT operation on the low-set stage
- Instantaneous high-set operation
- Circuit-breaker failure protection
- Disturbance recording
- Fault and event information
- Configurable trip and signalling outputs
- Optical communication for settings and data
- Non-volatile setting memory
- Continuous internal self-supervision
REJ513 is mainly useful where a dedicated overcurrent relay is required rather than a large multifunction feeder-protection device.
Applications
ABB REJ513 can be used for:
- Medium-voltage feeder protection
- Incoming feeder overcurrent protection
- Outgoing feeder protection
- Busbar protection
- Short-circuit protection
- Industrial power-distribution systems
- Utility substations
- Cable feeder protection
- Backup overcurrent protection
- Two-stage load shedding
- Switchgear protection panels
- Single-phase overcurrent applications
- Two-phase overcurrent applications
- Three-phase overcurrent applications
ABB specifically identifies REJ513 for basic protection of busbars and feeders in utility substations and industrial power-distribution systems.
ABB REJ513 Protection Stages
REJ513 has two main overcurrent stages.
Low-Set Overcurrent Stage
The low-set stage is used for normal overcurrent protection and can operate with either:
- Definite-time characteristic
- Inverse definite minimum time (IDMT) characteristic
High-Set Overcurrent Stage
The high-set stage is used for higher fault currents and can operate with:
- Instantaneous characteristic
- Definite-time characteristic
This two-stage arrangement allows the relay to provide both normal feeder overcurrent protection and faster operation for heavier short-circuit faults.
ABB REJ513 Part Number Identification
ABB documentation shows REJ513 order numbers in formats such as:
REJ513A 402-BAA
The complete code helps identify the actual hardware and supply arrangement of the installed relay.
For an ABB REJ513 replacement enquiry, send the full code exactly as shown on the relay marking strip or nameplate.
