ABB REC650 1MRK008514-CB
Product introduction
The ABB REC650 1MRK008514-CB is a advanced numerical protective relay designed for the protection, control, and monitoring of medium-voltage power distribution networks. As a key component in ABB’s Relion® product family, ABB REC650 1MRK008514-CB integrates multiple protection functions into a single device, ensuring reliable operation of feeders, transformers, and motors in 10-35 kV systems.
Unlike traditional electromechanical relays, ABB REC650 1MRK008514-CB leverages digital signal processing to deliver precise protection with customizable settings, adapting to diverse network configurations. Its compliance with the IEC 61850 standard enables seamless integration into smart grid environments, facilitating data exchange with SCADA systems and other intelligent electronic devices. Whether deployed in industrial plants, renewable energy facilities, or utility distribution networks, ABB REC650 1MRK008514-CB provides critical fault detection and isolation, minimizing downtime and enhancing grid stability.
Core advantages and technical highlights
Comprehensive protection capabilities: ABB REC650 1MRK008514-CB combines overcurrent, earth fault, distance, and thermal overload protection in one device, eliminating the need for multiple relays. Its distance protection function accurately detects faults within defined zones, enabling selective tripping to isolate only the affected section of the network—critical for maintaining power supply to other loads. In a manufacturing plant with a 20 kV distribution system, this selectivity reduces outage areas by up to 80% compared to traditional overcurrent-only protection.
Smart grid integration: With native support for IEC 61850, including GOOSE (Generic Object-Oriented Substation Event) and MMS (Manufacturing Message Specification), ABB REC650 1MRK008514-CB enables real-time data exchange and remote control in digital substations. This allows utilities to implement adaptive protection schemes that adjust settings based on network conditions, such as redistributing loads during peak hours. The relay’s web-based interface simplifies configuration and monitoring, reducing commissioning time by 30% compared to legacy devices.
Rugged design for harsh environments: ABB REC650 1MRK008514-CB operates reliably in temperatures ranging from -40°C to 70°C, making it suitable for outdoor substations and industrial facilities with extreme conditions. Its wide operating voltage range (24-250 V DC/AC) ensures compatibility with various power supply systems, while surge immunity (6 kV for contact discharge) protects against lightning-induced transients. This robustness ensures consistent performance in environments where dust, vibration, or temperature fluctuations are common.
Typical application scenarios
In a wind farm’s 35 kV collection network, ABB REC650 1MRK008514-CB protects each feeder connecting groups of wind turbines to the main substation. Its distance protection function quickly isolates faults on individual feeders, preventing cascading outages that could shut down the entire farm. The relay communicates via IEC 61850 with the substation’s SCADA system, providing real-time data on current, voltage, and fault events—enabling operators to diagnose issues without onsite visits. Its ability to withstand -40°C temperatures ensures reliable operation in cold-climate wind farms.
In an industrial park’s 10 kV distribution system, ABB REC650 1MRK008514-CB protects transformers supplying power to multiple factories. Its thermal overload protection monitors transformer temperature, issuing alarms or tripping before damage occurs during high-load periods. The relay’s Modbus TCP interface connects to the park’s energy management system, allowing coordinated load shedding to prevent overloads. This integration reduces transformer downtime by 50% and extends equipment lifespan by preventing overheating.

Installation, commissioning and maintenance instructions
Installation preparation: Mount ABB REC650 1MRK008514-CB on a flat panel using the provided brackets, ensuring a minimum of 50mm clearance around the device for ventilation. Connect control power (24-250 V DC/AC) using 1.5mm² shielded cable, with a 1A fuse for protection. Wire current transformers (CTs) and voltage transformers (VTs) to the analog inputs, ensuring correct polarity. Digital inputs/outputs require 0.5mm² cable, with shields grounded at the relay end. Use a torque screwdriver set to 1.5 Nm for terminal connections. Power off all systems during installation to avoid electrical hazards.
Maintenance suggestions: Inspect ABB REC650 1MRK008514-CB annually for loose connections, dust accumulation, and damage to the front panel. Clean the device with a dry cloth—avoid using compressed air to prevent dust ingress. Verify protection settings quarterly via the web interface, ensuring they match current network conditions. Test trip functionality annually using a relay test set to confirm correct operation. If communication faults occur, check Ethernet cables and IEC 61850 configuration before replacing components. Use only ABB-certified spare parts to maintain protection accuracy and safety certifications.
