Key specifications

• Number of poles: 3
• Rated current: 63A
• Breaking capacity: 25kA
• Trip unit type: Thermo-magnetic
• Design: Molded case circuit breaker

Installation should be performed by a qualified electrician in accordance with local electrical codes and safety regulations. The device is mounted onto a distribution board or panel, ensuring all terminal connections are tightened to the specified torque to prevent overheating. Once installed, the breaker can be manually operated using the front-facing toggle switch to connect or disconnect the power supply.

What to consider before purchase

• Verify that the 63A rated current matches your circuit requirements
• Ensure the 25kA breaking capacity is sufficient for your system's prospective fault current
• Confirm the physical dimensions fit your existing panel layout
• Check compatibility with your specific busbar or cable connection system

Usage recommendations

Regular inspection of the terminal connections and the operational status of the breaker is recommended to ensure continued safety. If the breaker trips, investigate the cause of the overload or short circuit before resetting the device.
