Residual current circuit breaker - 6 kA EFI6-P4 A 63/0.03 002061663

Reliable protection in your electrical installation

The residual current circuit breaker EFI6-P4 A 63/0.03 is a key element ensuring safety in every electrical circuit. It serves to protect against electric shock, both in the case of direct and indirect contact with live parts. Additionally, it protects devices from damage caused by overload or short circuit, minimizing the risk of fire. This four-pole circuit breaker with a rated current of 63A and sensitivity A, will find application in a wide spectrum of installations – from domestic to industrial.

Functionality and technical parameters

The circuit breaker is designed to operate in TN-S, TN-C-S, TT and IT networks, where the neutral and earth conductors are separated. Its construction based on type A technology guarantees reaction to both alternating residual currents and pulsating DC currents. The rated differential current at 30A level ensures effective protection against the effects of failures. The short-circuit strength at 6kA level confirms its reliability in extreme situations. Mounting is on a DIN rail, and the compact dimensions (width 4 modules, depth 68mm) facilitate installation even in crowded distribution boards.

• Versatility: Suitable for use with conductors with a cross-section from 1 to 25 mm², both solid and stranded.
• Wide temperature range: Trouble-free operation at temperatures from -25°C to 55°C, making it an ideal solution for both indoor and outdoor environments (with appropriate housing).
• Safety: Protection class IP20 provides basic protection against accidental contact.
• High quality: Made with attention to detail, using a fully automated production line – a guarantee of reliability and long life.
• Additional features: Equipped with a test button to check functionality and a contact position indicator for easy identification of the switch status (ON/OFF). The ability to seal the lever protects against unauthorized changes.

Application and compliance with standards

The residual current circuit breaker EFI6-P4 A 63/0.03 meets the requirements of DIN VDE 0100-482 and IEC 60364-4-482 standards regarding fire protection and provides effective protection against electric shock in accordance with safety regulations. Its versatility makes it ideal for use in:

• Domestic installations (apartments, single-family homes)
• Commercial buildings (offices, shops)
• Industrial facilities
• Main and sub-distribution boards
• Protection of lighting and socket circuits
