Description
The 1MRK002133-ABR02 is a medium-voltage feeder protection and control relay from ABB’s globally recognized Relion®615 series.Designed for mission-critical power distribution applications,it combines high-speed fault detection,advanced communication,and programmable logic in a compact,ruggedized housing.This digital relay delivers dependable protection,precise measurement,and seamless integration into modern smart grid and industrial automation infrastructures.
Application Scenarios
At a steel mill in the Midwest U.S.,frequent arc flash incidents on 13.8 kV motor feeders caused unplanned shutdowns and safety risks.After replacing legacy electromechanical relays with ABB 1MRK002133-ABR02,the plant achieved sub-20 ms fault clearance using GOOSE-based peer-to-peer tripping—reducing arc energy by over 70%and eliminating production losses from miscoordination.The 1MRK002133-ABR02 not only solved a critical safety pain point but also enabled remote monitoring and predictive maintenance through its embedded IEC 61850 data model,transforming reactive operations into proactive asset management.

Technical Principles and Innovative Values
Innovation Point 1:Dual-CPU architecture separates real-time protection(executed in<16 ms)from communication/HMI tasks,ensuring deterministic response even under heavy network load—unlike single-core competitors.
Innovation Point 2:Native IEC 61850 Edition 2 compliance with pre-certified GOOSE profiles allows plug-and-play interoperability in multi-vendor digital substations,cutting engineering time by up to 40%.
Innovation Point 3:Built-in configurable logic editor replaces external interposing relays,enabling custom schemes like auto-transfer,load shedding,or breaker health monitoring directly within the 1MRK002133-ABR02.
Innovation Point 4:Integrated cybersecurity features(role-based access,secure firmware update,audit logs)meet NERC CIP and IEC 62443 requirements out of the box—critical for utilities and critical infrastructure.
Innovation Point 5:Self-monitoring diagnostics cover power supply,analog front-end,memory,and communication ports,providing early warnings before failures occur—boosting system availability by>99.5%.
Application Cases and Industry Value
In a 220 MW solar farm in Spain,the 1MRK002133-ABR02 was deployed across 36 collector feeders to manage inverter-fed fault currents that traditional relays misinterpreted as normal operation.Thanks to its adaptive ground-fault detection and harmonic-immune algorithms,the 1MRK002133-ABR02 correctly identified 12 actual cable faults over 18 months—preventing equipment damage and avoiding an estimated€1.2M in lost revenue.Operators praised its intuitive LCD interface and PCM600 configuration workflow,reducing commissioning time per feeder from 4 hours to under 45 minutes.The relay’s accurate energy metering also supported performance-based O&M contracts with the asset owner.

Installation,Maintenance,and Full-Cycle Support
Installing the 1MRK002133-ABR02 requires minimal preparation:verify CT polarity,confirm auxiliary voltage class,and ensure Ethernet switches support VLAN tagging for GOOSE traffic.The unit supports hot commissioning—protection remains active during initial configuration via PCM600.Its wide operating temperature range and conformal-coated PCBs ensure reliability in dusty,humid,or high-vibration environments typical of mining or offshore platforms.
Routine maintenance is largely predictive:the relay continuously logs operational hours,trip counts,and self-test results,which can be pulled automatically into CMMS systems.In case of failure,modular design allows front-panel replacement in under 5 minutes without rewiring.All units shipped by our team undergo full functional validation—including simulated phase-to-ground faults and GOOSE latency tests—and come with a 12-month warranty,technical datasheets,and lifetime access to firmware archives.Our certified ABB-trained engineers provide remote support for configuration,troubleshooting,and cybersecurity hardening.
