Residual current circuit breaker P 312 2P C 16 A 30 mA Type A 10 kA DX3 series 411296

Protection and Safety in One Device

The residual current circuit breaker P 312 2P C 16 A 30 mA Type A 10kA from the DX3 series is a reliable solution providing comprehensive protection for electrical installations. It combines the functions of an overcurrent and residual current device, safeguarding against the effects of overloads, short circuits, and electric shocks. This is an ideal choice for both installers and end-users who value safety and convenience.

Functionality and Specifications

This two-pole (2P) circuit breaker with a rated current of 16 A offers high operational efficiency thanks to its C characteristic. This means it allows brief current surges above the rated value without unnecessary tripping—particularly important when starting electric motors. The rated residual current of 30 mA ensures rapid response upon detecting earth leakage, minimizing the risk of electric shock. With a short-circuit breaking capacity of 10 kA, it guarantees effective disconnection in the event of a short circuit. Equipped with a mechanical lock that prevents accidental re-energizing after an automatic trip due to a fault.

Installation and Compatibility

The P 312 DX3 breaker is designed for mounting on a TH35 rail, simplifying and accelerating installation. Its compact dimensions (4 modules wide, 44 mm depth) enable efficient use of space in distribution boards. The device complies with IEC/EN 61009-1 and EN 61009 standards, confirming its safety and reliability. It is compatible with the HX³ Optimal Power Distribution System up to 125 A, and a wide range of available accessories (auxiliary contacts, signaling contacts, trip units) enhances its functionality and adaptability to specific installation needs. It supports single-core conductor cross-sections from 0.75 to 16 mm² and multi-core conductors from 0.75 to 10 mm², ensuring flexible connection options for various cable types.
