Core Functionalities

1. Circuit Protection
   • Automatically disconnects power during overloads or short circuits to prevent equipment damage and fire hazards.
   • C-curve tripping balances protection for resistive and inductive loads (e.g., lighting, motors).
2. User Safety
   • Ensures safe isolation of circuits during maintenance or repairs.
   • Arc-quenching design minimizes arc flash risks during fault interruption.
3. Space-Saving Installation
   • Compact width (17.5 mm per pole) optimizes space in distribution boards.
   • Tool-free DIN rail mounting simplifies installation.
4. Compatibility
   • Integrates seamlessly with ABB’s System Pro M compact® accessories (e.g., shunt releases, auxiliary contacts).
   • Compatible with standard DIN rail enclosures and panel designs.

Typical Applications

• Residential: Protection of lighting circuits, sockets, and household appliances.
• Commercial: Use in office buildings, retail spaces, and HVAC control panels.
• Industrial: Integration into machinery, conveyor systems, and motor control centers (MCCs).
• Renewable Energy: Circuit protection in solar PV distribution systems.

Advantages

• Reliability: Precision-engineered tripping mechanisms ensure consistent performance.
• Durability: Robust construction for long-term operation in diverse environments.
• Flexibility: Modular design supports expansion with auxiliary modules (e.g., alarms).
