Residual current circuit breaker P 314 4P C 32 A 300 mA Type A DX3 series 411242

Advanced Protection for Electrical Installations with Legrand DX³ Residual Current Circuit Breaker

This four-pole residual current circuit breaker (RCCB) from Legrand’s DX³ series combines overload and short-circuit protection with electric shock prevention. The device provides comprehensive protection for electrical circuits in residential, commercial, and industrial buildings. Its use ensures safety and reliability of the entire installation.

The P 314 breaker, rated at 32A and with a sensitivity of 300mA (Type A), is designed to protect against both alternating and direct leakage currents, making it an ideal solution for circuits powering equipment that generates disturbances—such as washing machines, dishwashers, and electric ovens. The C characteristic ensures delayed tripping during brief overloads, minimizing unnecessary disconnections when starting high-power devices.

Advantages and Features

• Two Functions in One Device: Integration of residual current and overcurrent protection saves space in the distribution board and simplifies installation.
• High Short-Circuit Capacity: Rated short-circuit breaking capacity up to 10 kA (IEC/EN 61009-1) ensures effective disconnection during short circuits, reducing the risk of damage and fire. Rated breaking capacity Icn is 6 kA in accordance with EN 61009-1.
• Test Button: Built-in test button enables regular verification of the RCCB’s proper operation, ensuring continuous protection.
• Lockout Mechanism: A locking system prevents accidental re-energizing after tripping, enhancing safety during maintenance work.
• Versatile Application: Compatible with the Optimal Energy Distribution HX³ system and various auxiliary devices such as auxiliary contacts and signaling units.
• User Safety: IP20 protection rating prevents accidental contact with live parts.
• Installation: 4-module width facilitates mounting in standard distribution boards. Mounting depth is 44 mm.
