Residual current circuit breaker EFI-P2 AC 63/0.03 002061213

Reliable protection of electrical installations

The EFI-P2 AC 63/0.03 residual current circuit breaker is a key element protecting the electrical installation from the effects of electric shock and potential fire hazards. The device is designed for use in TN-S, TN-C-S, TT and IT networks where the neutral and earth conductors are separated. Its task is to quickly detect leakage currents and disconnect the circuit, minimizing the risk to people and property.

Functionality and application

This circuit breaker, with a rated current of 63A and a sensitivity of 0.03A (AC), is perfect for protecting single-phase circuits with higher loads. The AC type means that the device reacts to alternating differential currents, which is particularly important for protection against direct and indirect contact. This ensures effective protection for both end users and the electrical installation. DIN rail mounting simplifies integration with the existing distribution board.

Construction and parameters

The circuit breaker is characterized by a solid construction and high technical parameters. The short-circuit strength of 10 kA guarantees its resistance to damage in the event of a short circuit. Compact dimensions – a width of 2 modules – allow for easy mounting even in crowded distribution boards. Terminals allow connection of multi-core and solid-core wires with a cross-section of 25 mm². The IP20 degree of protection provides basic protection against accidental contact. Additionally, the circuit breaker has a contact position indicator, making it easier to identify the device status (ON/OFF).

The circuit breaker allows protection of circuits with higher power consumption thanks to the rated current of 63A. A quick reaction to leakage currents, protecting against electric shock, is ensured by a current sensitivity of 0.03A (30mA). The device reacts to alternating differential currents (AC type), providing comprehensive protection. Short-circuit strength at the level of 10 kA guarantees resistance to damage during short circuits. DIN rail mounting simplifies integration with the existing electrical installation, and terminals allow connection of wires with a cross-section of up to 25 mm². The two-pole design (2P) is ideal for single-phase circuits.
