Description
ABB RER133 – Recloser Control IED for reliable distribution automation and SCADA integration
ABB RER133 is a recloser control IED designed for medium-voltage distribution networks, typically used to automate pole-mounted reclosers and improve feeder reliability. From my experience, utilities choose the RER 1xx family when they want dependable auto-reclose logic, clear local HMI, and straightforward integration to SCADA with IEC 61850 or DNP3. You might notice that it balances protection, control and communications in a compact, panel-mount form—ideal for retrofit projects and new builds alike.
In many cases, the RER133 is deployed at feeder laterals or tie points to speed up fault isolation and service restoration. Disturbance/event records and flexible logic help engineers fine-tune reclosing sequences, while standard utility protocols keep the device open and easy to integrate.

Key Features
- Recloser automation – Fast auto-reclose logic with configurable sequences to reduce outage minutes and improve SAIDI/SAIFI.
- Protection and control in one unit – Typical recloser functions (overcurrent, directional elements, blocking, lockout) plus interlocking and manual/remote control.
- SCADA-ready communications – IEC 61850 for station bus; DNP3 and Modbus commonly available for legacy systems, helping mixed-fleet deployments.
- Event and disturbance recording – Time-stamped events and oscillography support post-fault analysis and continuous improvement of reclosing strategy.
- Wide auxiliary supply options – Typically supports utility DC systems and universal AC/DC ranges, simplifying standardization across sites.
- Local HMI – Clear display, function keys and indication LEDs for quick diagnostics and safe field operation.
- Flexible I/O – Binary inputs/outputs and standard CT/VT measurement inputs to interface with most recloser panels and sensors.
- Time synchronization – SNTP commonly supported; IRIG-B available in many builds for precise event correlation.
- Cybersecurity-minded design – Role-based access and password management options that align with typical utility policies.

Real-world usage
A regional utility replaced legacy controls on several pole-top reclosers with RER133. Within the first storm season, they reported faster sectionalizing and fewer truck rolls—SCADA operators could remotely block reclosing during maintenance and pull disturbance records the same day. It seems to be a practical upgrade when the fleet mixes old and new reclosers, because protocol flexibility keeps integration smooth.

Installation & Maintenance
- Environment – Install in a sealed, ventilated cabinet (IP54/NEMA 3R or better for outdoor). Avoid direct solar heating; provide cable glands and drip loops.
- Mounting – Panel flush-mount with recommended cutout and gasket. Keep clearance for wiring and HMI access.
- Wiring – Use shielded, twisted-pair for serial comms; CAT5e/CAT6 for Ethernet. Ground shields at one end; maintain CT shorting facilities for safe service.
- Power – Match auxiliary supply option (DC or AC/DC). Provide surge protection on aux supply and I/O in MV yards.
- Networking – Define VLANs and roles; set strong credentials. Time-sync via SNTP or IRIG‑B to keep event stamps accurate.
- Routine maintenance – Annual functional tests of protection and reclosing logic; periodic I/O check; back up settings/IED configuration; update firmware per ABB advisories.
- Calibration & cleaning – Verify CT/VT scaling during commissioning; keep HMI and vents clean; inspect terminals for torque and corrosion.
