Residual current circuit breaker P 314 4P C 10 A 30 mA type AC, DX3 series 411185

Protection and Safety in One Device

The residual current circuit breaker P 314 4P C 10 A 30 mA AC 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 short circuits, overloads, and electric shocks. This is an ideal choice for both electricians and end-users who value safety and convenience.

Design and Application

This four-pole breaker (4P), rated at 10 A with characteristic C, is designed for operation in circuits with a voltage of 400 V and a frequency of 50 Hz. The C characteristic allows it to respond more slowly to brief current surges, making it well-suited for starting motor-driven equipment. The rated residual current of 30 mA ensures effective protection against electric shock. The breaker features a separable N-pole, enhancing both functionality and safety of the installation.

Advantages and Benefits

• Comprehensive protection: Integration of overcurrent and residual current protection in a single device.
• High breaking capacity: Rated short-circuit breaking capacity (Icn) is 6 kA, and switching capacity according to IEC 60947-2 is 10 kA — ensuring effective protection in the event of a short circuit.
• User convenience: Equipped with a test button to verify proper operation.
• Compact dimensions: 4-module width allows optimal space utilization in the distribution board (mounting depth: 44 mm).
• Safety: Features a lockout mechanism preventing accidental re-energizing after a fault-induced trip.
• Versatility: Compatible with auxiliary equipment such as auxiliary and signaling contacts and undervoltage releases.
• Type AC: Designed to detect sinusoidal residual currents typical of most electrical appliances.
• Protection rating IP20: Protects against finger contact and solid objects larger than 12.5 mm in diameter.

DX³ breakers are compatible with the HX³ Optimal Energy Distribution System, enabling wireless integration into electrical installations up to 125 A. This is a modern solution for demanding electrical installations.
