Residual current device P 302 2P 16 A 10 mA type AC, DX3 series 411500

Safety and Protection in Your Electrical Installation

This two-pole residual current device (RCD) P 302 from the DX³ series is a critical component ensuring safety in every electrical circuit. Designed to protect people from electric shock and equipment from the effects of earth faults, it provides reliable protection in both residential and commercial environments. Manufactured by the renowned company Legrand, this model combines high build quality with advanced features.

Specifications and Applications

This device, rated at 16 A and with 10 mA sensitivity (Type AC), effectively detects sinusoidal leakage currents, ensuring rapid response during faults. Mounting on a DIN rail (standard TH35) simplifies installation and integration with existing electrical infrastructure. Its compact 2-module width allows efficient use of space in distribution boards. Designed for operation at 230 V and 50 Hz, it is ideal for protecting lighting, socket, and other electrical load circuits. The use of Type AC characteristic means the device responds to alternating currents, making it suitable for the vast majority of standard residential and industrial applications.

Construction and Additional Features

The P 302 features a mechanical lock that prevents accidental switching on or off, enhancing operational safety. The ability to install additional accessories—auxiliary contacts, trip units, and remote control drives—allows the device’s functionality to be customized to specific installation requirements. The housing, made from high-quality materials (color RAL 7035), ensures durability and resistance to mechanical damage. With a short-circuit withstand rating of 10 kA, it guarantees reliable operation even under overload conditions. Terminal connections support single-core cables from 0.75 mm² to 50 mm² and multi-core cables from 0.75 mm² to 35 mm², providing flexibility when connecting various cable types. Additionally, the device is resistant to impulse currents up to 0.25 kA and features an IP20 protection rating.
