Residual current circuit breaker 3P+N 63A 300mA 6kA AC S CPC463J

Safety and protection in your installation

Hager 3P+N 63A 300mA residual current circuit breaker (RCCB) is a key element ensuring safety in electrical installations. Its function is to quickly detect and disconnect circuits in the event of a current leakage to earth, minimizing the risk of electric shock and equipment damage. This is a reliable solution for both installers and end-users, guaranteeing a high level of protection.

Functionality and parameters

This four-pole (3P+N) circuit breaker, mounted on a DIN rail, is designed to operate in AC networks with a rated voltage of 400V. The rated current of 63A and sensitivity of 300mA make it ideal for protecting circuits with higher loads. The short-circuit strength of 6kA provides resistance to sudden current surges, and the rated insulation voltage Ui of 500V guarantees safe operation in various conditions.

• Rated current of 63A allows for protection of circuits with higher power consumption.
• Sensitivity at 300mA ensures a quick response to leakage currents, protecting against electric shock.
• Short-circuit strength (Icw) of 6kA guarantees resistance to sudden current surges, increasing reliability.
• DIN rail mounting simplifies and speeds up installation in electrical panels.
• Rated impulse withstand voltage Uimp of 4kV provides protection against overvoltages.

Construction and application

The circuit breaker is characterized by a compact design occupying 4 modules wide, which facilitates its installation even in tight switchboards. The cross-section of the connectable solid conductor up to 25mm² and stranded conductor up to 16mm² provides flexibility in cable selection. The device is intended for use in three-phase installations, providing comprehensive protection in residential, commercial and industrial buildings. Thanks to the wide range of operating temperatures (-25°C to +40°C) it can be used in various environmental conditions. Additionally, the lack of locking provides convenient use and servicing.

This Hager residual current circuit breaker is an investment in the safety and reliability of your electrical installation. It provides effective protection against electric shock and equipment damage, giving you and your loved ones peace of mind.
