Features Schneider A9F94440

1. High Breaking Capacity:

   • The 15 kA breaking capacity (at 415 VAC) according to IEC 60898-1 and the 20 kA capacity according to IEC 60947-2 ensure that the Acti9 iC60L circuit breaker can manage high fault currents, providing effective protection for electrical systems and devices against short circuits and overloads.

2. C Curve:

   • The C curve characteristic indicates that the breaker trips between 5 to 10 times the rated current. This curve type is perfect for applications with moderate inrush currents, such as motors, lighting circuits, and heating systems, where transient current spikes occur during startup.

3. Four-Pole Design (4P):

   • The 4P (four-pole) configuration is ideal for protecting three-phase electrical systems with a neutral conductor. It ensures balanced protection for all four conductors (three phases and the neutral) in industrial and commercial setups.

4. Thermal-Magnetic Trip Mechanism:

   • The thermal-magnetic trip mechanism provides dual protection:

     • Thermal protection for overload conditions (gradual overcurrent).

     • Magnetic protection for short-circuit events (instantaneous high current).

   • This combination ensures both types of faults are detected and cleared efficiently.

5. Compact Design:

   • The Acti9 iC60L MCB is designed to be compact and space-saving, making it suitable for installation in standard distribution boards, panel boards, and electrical enclosures without occupying unnecessary space.

6. Long Life and Reliability:

   • Schneider’s Acti9 range is known for its long-lasting reliability. The iC60L circuit breaker is designed to provide consistent protection over time, ensuring operational safety in both residential and industrial applications.

7. Standards Compliance:

   • The circuit breaker meets the safety and performance requirements of both IEC 60898-1 (for residential and light commercial use) and IEC 60947-2 (for industrial use), ensuring compliance with international electrical safety standards.

Applications:

• Industrial Electrical Systems: Ideal for protecting three-phase systems in industrial environments, where high reliability and protection are critical for equipment and machinery.

• Commercial Installations: Suitable for use in commercial buildings, offices, and retail spaces with complex electrical distribution systems that require four-pole protection.

• Residential Use: While typically used in industrial and commercial settings, this breaker can also be used in residential installations that require four-pole protection, such as in larger HVAC systems or certain motorized appliances.

• Motor Protection: Protects motors and equipment with moderate inrush currents, ensuring safety during startup and normal operation.

• Distribution Panels: Perfect for use in low-voltage distribution boards and electrical panels, offering protection from overloads and short circuits in complex electrical networks.
