• Protective function types: Overload (Inverse Time), Short Circuit (Instantaneous), Phase Imbalance, Neutral Loss
• Input signals: Current signals from current transformers (0–5 A), voltage signals (100 V, 220 V AC)
• Response time: ≤ 50 ms (for short circuits)
• Output contacts: 4 relay contacts (configurable normally open/normally closed), maximum current 5 A
• Operating temperature: -25°C to +70°C
• Power supply: 110–220 V AC or 24–48 V DC (wide range)
• Protection: ESD protection (±25 kV), pulse interference protection (IEC 61000-4-4), IP40 enclosure rating
• Construction: DIN rail mounting, metal housing, sealed signal and power connectors

Advantages and Features

• Multifunction integration: ABB 1MRK002122-ABR02 combines multiple protective functions in a single module, reducing the number of devices in distribution cabinets and simplifying maintenance.
• High reliability: Stable operation across a wide temperature range (-25°C to +70°C) and resistance to external interference ensure effectiveness in harsh operating environments (e.g., industrial facilities or rural grids).
• Flexible configuration: Protective parameters (delay time, trip thresholds) can be adjusted via local switches or software, adapting to different scenarios.
• Easy integration: Standard interfaces and compatibility with various current and voltage transformers facilitate connection to existing grid systems.
• Clear status indication: LED indicators show module status (normal, fault, module error) and fault type.

Application Cases

• Industrial grids: In factory distribution systems, ABB 1MRK002122-ABR02 protects cabinets from overloads caused by large motor startups and short circuits in cables.
• Rural grids: Used to protect supply lines against overloads during peak demand periods (e.g., irrigation seasons) and phase imbalances from uneven load distribution.
• Residential complexes: Installed in multi-story building inlet cabinets to prevent fires and appliance damage from socket circuit short circuits and overloads.
• Mining enterprises: Deployed in mobile drilling platform power stations to protect generators and cables from faults under vibration and extreme temperatures.

Selection Suggestions and Precautions

• When selecting ABB 1MRK002122-ABR02, ensure its protective functions match your grid requirements (information available via the product link for ABB 1MRK002122-ABR02).
• For accurate threshold settings, calibrate current and voltage inputs using standard instruments.
• During installation, keep the module away from strong electromagnetic sources (e.g., transformers, motors) to avoid false protection triggers.
• Regularly check status indicators and test relay contacts to ensure proper operation.
• For high-reliability systems, equip ABB 1MRK002122-ABR02 with backup power to prevent module failure during power outages.
