Residual current circuit breaker 3P+N 63A 300mA 6kA AC CFC463J

Safety and protection in your installation

Residual Current Device (RCD) 3P+N 63A 300mA 6kA AC is a key element ensuring safety in electrical installations. This device, manufactured by Hager, effectively protects against electric shock and limits the consequences of damage and potential fire hazards. Its operation is based on the rapid detection of leakage currents and automatic disconnection of the circuit, minimizing the risk to people and equipment.

Construction and application

This RCD is designed for mounting on a DIN rail and is used in three-phase installations with a rated voltage of 400V. The rated current of 63A and sensitivity of 300mA make it an ideal solution for both home installations and commercial or industrial facilities. The 3P+N construction (three phase poles plus neutral pole) provides comprehensive protection for the entire circuit. High short-circuit strength at 6kA guarantees reliable operation even in the event of sudden overvoltages.

Key features and benefits

• Fast response: AC sensitivity ensures effective detection of leakage currents, minimizing the risk of electric shock.
• High resistance: Short-circuit strength of 6kA protects the RCD from damage during short circuits, ensuring continuity of supply (after removing the cause of the short circuit).
• Easy installation: DIN rail mounting simplifies and speeds up installation, saving time and labor costs.
• Wide range of applications: Suitable for protecting circuits with a conductor cross-section from 1 mm² to 25 mm² (solid core) and from 1 mm² to 16 mm² (stranded).
• Solid construction: Made of high-quality materials, guaranteeing long-lasting and reliable operation.
• Safety confirmed by standards: Compliance with standards ensures a high level of safety.
• Modular width: Occupies 4 modules on the DIN rail, allowing for efficient use of space in the distribution board.

Additionally, the RCD has a protection degree of IP20, which means protection against touching with a finger and against the ingress of solid objects larger than 12.5 mm. The ambient temperature in operating conditions ranges from -25°C to +40°C, allowing it to be used in various environmental conditions. The possibility of additional equipment allows the RCD to be adapted to specific installation needs.
