Key Features

1. Triple Pole Protection (3P):
   Offers simultaneous protection for all three phases in a three-phase electrical system. Ideal for distribution boards and motor circuits.

2. C Curve Tripping Characteristic:
   Designed to trip at 5 to 10 times the rated current, the C curve is ideal for general-purpose circuits, including lighting, sockets, and small inductive loads with moderate inrush currents.

3. High Breaking Capacity:
   With a 6 kA rating (IEC 60898-1) and 10 kA rating (IEC 60947-2), this MCB ensures strong protection in both residential and industrial electrical networks, especially where fault levels may be high.

4. Modular DIN Rail Mounting:
   Easy to install and replace using standard DIN rail systems. Compatible with other Acti9 protection and control devices for a unified panel solution.

5. Ergonomic and Safe Design:
   Finger-safe terminals (IP20) and dual terminals ensure both safety and ease of wiring. Label holder for clear circuit identification.

6. Long Mechanical and Electrical Life:
   Engineered for durability, with a mechanical life exceeding 20,000 operations and an electrical life of up to 10,000 operations depending on load conditions.

7. Visible Contact Indication (VisiTrip & VisiSafe):
   The VisiTrip indicator allows quick fault identification, while VisiSafe ensures disconnection of power during maintenance (available on certain versions of the Acti9 range).

Applications

1. Industrial Electrical Panels:
   Suitable for protecting motor circuits, industrial lighting, and power distribution boards in factories, warehouses, and workshops.

2. Commercial Buildings:
   Used in shopping malls, office buildings, and data centers to safeguard against circuit faults in lighting, HVAC, and general-purpose power circuits.

3. Infrastructure Projects:
   Applied in transportation, public utilities, and infrastructure systems where dependable protection and fast maintenance are critical.

4. Renewable Energy Installations:
   Can be used in solar PV distribution boards and wind energy systems, especially in three-phase setups requiring dependable circuit protection.

5. Residential High-Load Circuits:
   Appropriate for large residential systems where high current three-phase appliances or distribution circuits are used.
