Residual Current Circuit Breaker P312 2P C 6A 30mA TYPE AC DX3 411010

Residual Current Breaker with Overcurrent Protection (RCBO) P312 2P C 6A 30mA is a key element ensuring safety in electrical installations. Using this device minimizes the risk of electric shock and protects against the effects of overloads and short circuits. It is a reliable solution for both installers and end-users looking for comprehensive protection.

Protection and functionality

This two-pole switch combines the functions of an overcurrent circuit breaker (C characteristic) and a residual current device (30mA, type AC). This means that it not only protects the circuit against overload and short circuit – like most switches in this class – but also effectively detects earth leakage currents, providing protection for people. The C characteristic allows it to react more slowly to short current surges, making it well-suited for starting devices with a motor. The ability to simultaneously disconnect the N pole increases safety in the event of a failure.

Installation and technical parameters

The P312 switch is designed for flush mounting and occupies 2 modules in a distribution board. Its embedding depth is 44 mm. The possibility of connecting single-wire conductors with a cross-section of 0.75-16 mm² and multi-wire conductors 0.75-10 mm² provides flexibility during installation. The device has a protection degree of IP20, which means protection against touching with a finger and solid objects larger than 12.5 mm. The energy limitation class is 3, and the pollution degree is 2 – parameters important when designing protection systems. The rated short-circuit breaking capacity Icn is 6 kA, which guarantees effective disconnection of the circuit in the event of a short circuit.

Applications and compliance with standards

The RCBO P312 is used to protect circuits with a rated current of 6A, e.g. lighting, electrical outlets or household appliances. It meets the requirements of EN 61009-1 and IEC 60947-2 standards, which confirms its high quality and safety of use. It has a lock preventing accidental switching on after switching off due to a failure.
