Residual current circuit breaker P 312 2P B 16 A 30 mA Type A 10 kA DX3 series 411288

Protection and Reliability in Your Electrical Installation

The P 312 2P B 16 A 30 mA Type A 10kA residual current circuit breaker from the DX³ series is a key component ensuring safety and protection in every electrical circuit. It combines the functions of an overcurrent and residual current device, providing comprehensive protection against the effects of short circuits, overloads, and electric shocks. This solution is ideal for both professional installers and end-users who value reliability and peace of mind.

Functionality and Design

This two-pole (2P) circuit breaker, rated at 16 A, is designed for use in 230 V AC installations. The B characteristic ensures rapid response to overloads and short circuits, while allowing smooth startup of motor-driven devices that generate temporary current surges. The rated residual current of 30 mA guarantees effective protection against electric shock by detecting even the smallest earth leakage currents. A short-circuit breaking capacity of 10 kA ensures safety even during severe faults.

The breaker is designed for easy installation on a TH35 (DIN rail). Its compact dimensions (4 modules wide, mounting depth of 44 mm) allow optimal space utilization in distribution boards. Additionally, the mechanism lock prevents accidental re-energizing after tripping, enhancing safety during maintenance or repair.

Applications and Benefits

• Comprehensive Protection: Combined overcurrent and residual current protection in a single device — saves space and cost.
• Safe Operation: 30 mA residual current ensures rapid response to leakage currents, minimizing shock risk.
• Versatility: Type A makes it suitable for protecting circuits with devices generating pulsating DC currents — common in modern installations.
• Easy Installation: Quick DIN rail mounting via snap-in clips — saves time during installation.
• Status Indicator: Clear trip indicator simplifies fault diagnosis and rapid power restoration.
• Mechanism Lock: Ensures safety during maintenance and repair by preventing accidental re-energizing.
• Conductor Cross-Sections: Supports single-core conductors from 0.75 mm² to 16 mm² and multi-core conductors from 0.75 mm² to 10 mm².
• Compliance with Standards: Meets requirements of IEC/EN 61009-1 and VDE 0664-20, guaranteeing the highest level of safety and reliability.

The P 312 DX³ is a robust and reliable solution for anyone who cares about the safety of their electrical installation and user comfort. It’s an investment in peace of mind and protection against potential electrical hazards.
