Residual current circuit breaker 6kA PF6-63/4/03 286514

Protection and safety in electrical installations

Residual current circuit breaker (RCCB) is a key element of every modern electrical installation, providing protection for people and equipment against the effects of leakage and short-circuit currents. Model PF6-63/4/03, with a rated current of 63A and a tripping current of 0.3A, is designed to operate in AC (alternating current) systems with a voltage of 400V. Its four-pole design makes it ideal for protecting three-phase circuits.

Construction and application

This circuit breaker is mounted on a DIN rail and is 4 modules wide. It provides effective protection against electric shock by detecting even small differential currents. The ability to connect multi-wire conductors with a cross-section of 1.5 to 16 mm² and solid conductors from 1.5 to 35 mm² provides great flexibility during installation. The locking mechanism of the circuit breaker increases safety by preventing accidental switching on after switching off due to a failure.

Key features and benefits

• High resistance to interference: AC sensitivity ensures reliable operation in typical electrical installation operating conditions.
• Wide range of applications: Suitable for protecting circuits in residential, commercial and industrial buildings.
• Installation flexibility: The ability to connect wires of different cross-sections makes it easier to integrate with existing installations.
• Safety of use: The locking mechanism prevents accidental re-switching of a damaged circuit.
• Durability and reliability: Short-circuit strength at the level of 6kA guarantees stable operation even in the event of overloads.
• Regular testing: Remember to perform functional tests of the circuit breaker at least twice a year – this guarantees its proper operation when needed.
• Convenient wire connection: The possibility of routing the N conductor on both sides facilitates and speeds up installation work.
• Resistance to external conditions: Operation at temperatures from -25°C to 60°C and a degree of protection of IP20 allow for use in various working environments.

This residual current circuit breaker is a solid and reliable solution for anyone who cares about the electrical safety of their installation. It provides not only protection against electric shock, but also minimizes the risk of equipment damage caused by leakage currents.
