• C Curve Tripping
  Designed for general-purpose circuits with moderate surge currents like mixed lighting, small motors, and HVAC systems.

• Thermal-Magnetic Trip Mechanism
  Combines thermal protection against overloads and magnetic protection against short circuits.

• Modular, Space-Efficient Design
  Compact size for high-density installations in modern electrical distribution boards.

• Easy DIN Rail Mounting
  Quick and reliable installation with standard modular enclosures and accessories.

• Durable Construction
  Designed for long-lasting, stable performance even under intensive operational demands.

Applications:

• Industrial Electrical Panels
  Provides comprehensive circuit protection in three-phase plus neutral systems across various industrial sectors.

• Commercial Buildings
