Residual current circuit breaker EFI-P2 AC 63/0.3 002061233

Protection and safety in electrical installations

The EFI-P2 AC 63/0.3 residual current circuit breaker (RCCB) is a key element ensuring safety in every electrical installation. It serves to protect against electric shock, both in the case of direct and indirect contact with live parts. Additionally, it protects devices from potential fire hazards resulting from insulation damage. Its application is wide-ranging – from domestic installations, through commercial facilities, to industrial ones.

This two-pole residual current circuit breaker is designed to operate in TN-S, TN-C-S, TT and IT networks, where the neutral and earth conductors are separated. The selection of the appropriate residual current value (IΔn) depends on the specifics of the application – values ≤ 30 mA are recommended for additional protection (direct contact), and ≤ 300 mA for protection against indirect contact (damage). Remember that according to DIN VDE 0100-482 and IEC 60364-4-482 standards, all cables and cores in TN and TT systems should be protected by circuit breakers with a residual current IΔn ≤ 300 mA.

Characteristics and application

The EFI-P2 AC circuit breaker is characterized by high reliability and precision of operation. Designed for mounting on a DIN rail, it occupies only 2 modules in width, allowing for optimal use of space in the distribution board. Its rated current is 63 A, and the rated residual current is 0.3 A. The short-circuit strength of 10 kA guarantees its stable operation even in difficult operating conditions. The AC type application means sensitivity to alternating residual currents – an ideal solution for most standard applications.

Thanks to its solid construction and high-quality materials, this circuit breaker ensures long-lasting and trouble-free operation. The test button allows for regular checking of the device's functionality, and the contact position indicator facilitates identification of the circuit breaker status (ON/OFF). Additional terminal protection against touch increases safety during installation and maintenance. The ability to seal the lever and mount accessories (auxiliary contacts, release devices) expands its functionality and adapts it to individual installation needs.
