Residual current circuit breaker EFI-P4 AC 63/0.03 002061613

Safety and protection in your electrical installation

The EFI-P4 AC 63/0.03 residual current circuit breaker (RCCB) is a key element ensuring the safety of using the electrical installation. Its task is to protect against electric shock, both in the case of direct and indirect contact with live conductors. Additionally, it protects devices from damage caused by overload or short circuit. This is a reliable protection for homes, offices and industrial facilities.

Universal application and high performance

This four-pole (4P) circuit breaker with a rated current of 63A and a sensitivity of 0.03A is designed to operate in TN-S, TN-C-S, TT and IT networks. Its AC-based technology ensures that it reacts to alternating differential currents, providing effective protection against dangerous situations. Short-circuit strength at the level of 10 kA guarantees stable operation even in the event of large voltage surges. DIN rail mounting simplifies installation and integration with existing electrical infrastructure.

Solid construction and durability

The circuit breaker has been designed with long-term and trouble-free operation in mind. Its housing with a protection degree of IP20 protects against accidental contact and the influence of external factors. Compact dimensions (4 module width) allow for easy placement in a distribution box. Made of high-quality materials, it ensures reliability and durability for years of use. The cross-section of the connected multi-core and solid-core wire is 25 mm², which allows connection of wires of appropriate thickness. Additionally, the impulse withstand voltage is 0.4 kA, which increases its reliability in difficult working conditions.
