Residual current device P 302 2P 40 A 30 mA Type A DX3 series 411555

Safety and Protection in Your Electrical Installation

This two-pole residual current device (RCD) from the DX³ series is a critical component ensuring safe operation of electrical installations. It protects against electric shock and prevents fires caused by earth fault currents. The device is designed to safeguard both people and equipment by detecting imbalances in current flow.

The P 302 RCD, rated at 40A and with 30mA sensitivity (Type A), effectively detects leakage currents, ensuring rapid response and disconnection in case of a fault. Its construction based on proven Legrand technology guarantees reliability and long-term performance. Additionally, the built-in lockout mechanism prevents accidental re-energizing after tripping, enhancing overall safety.

Installation and Application

This residual current device is designed for DIN rail mounting, simplifying installation in electrical distribution boards. Its compact dimensions — 2 modules wide and 44 mm deep — allow efficient use of space within the distribution cabinet. Compatible with devices operating at 230V AC and 50Hz frequency, it is suitable for both residential and commercial installations. The ability to connect conductors with cross-sections from 0.75 mm² to 50 mm² (single-core) and from 0.75 mm² to 35 mm² (multi-core) ensures installation flexibility.
