Description
The ABB REC650 (order / part number 1MRK008514-CB) is an Intelligent Electronic Device (IED) from the ABB / Hitachi Energy Relion 650 series, engineered for bay control, apparatus management, and integrated protection in sub-transmission and distribution substations.
The REC650 provides an off-the-shelf, type-tested control and protection solution designed primarily for single-breaker applications in single and double busbar arrangements. It integrates apparatus control (select-before-operate), synchrocheck, automatic reclosing, line backup protection, and comprehensive monitoring into a compact hardware footprint.

Core Features & Operating Capabilities
- Apparatus Control & Interlocking: Controls up to 10 primary switching devices (circuit breakers, disconnectors, earthing switches) using secure “Select-Before-Operate” (SBO) logic to prevent human error.
- Fast Horizontal Interlocking via GOOSE: Utilizes IEC 61850 GOOSE messaging for fast, station-wide reservation and interlocking without extensive inter-panel hardwiring.
- Integrated Protection & Auto-Reclose: Combines phase-isolated protection elements, backup overcurrent/distance algorithms, auto-reclosing (SMBRREC), and synchrocheck supervision.
- Pre-Configured Parameters: Delivered with factory pre-sets, drastically reducing commissioning times and setup parameter complexity in PCM600.
- Condition & Health Supervision: Continuously monitors circuit breaker health, trip circuit integrity, power supply rails, and gas/insulation status.
