Residual current device P 302 2P 25 A 300 mA Type A DX3 series 411569

Safety and Protection in Your Electrical Installation

This two-pole residual current device (RCD) P 302 from the DX3 series by Legrand is a critical component ensuring safety in every electrical circuit. It protects users from electric shock and safeguards equipment against the effects of short circuits and overloads. With a rated current of 25A and a sensitivity of 300mA, it is an ideal solution for protecting circuits with medium load.

Functionality and Installation

The device is designed for DIN rail mounting, simplifying installation and replacement. Its compact 2-module width allows efficient use of space in the distribution board. The option to add supplementary accessories—such as auxiliary or signaling contacts—enhances its functionality and enables customization to meet specific installation requirements. The integrated test button allows regular verification of proper operation, which is essential for continuous protection.

Specifications and Parameters

The P 302 RCD features high impulse current resistance (0.25 kA) and a short-circuit withstand rating of 10 kA, ensuring reliable performance even under demanding conditions. It is designed to operate in temperatures ranging from -25°C to 60°C and complies with safety standards, featuring an IP20 protection rating. The rated insulation voltage (Ui) is 250V, and the rated voltage is 230V AC. The cross-section for single-core conductors ranges from 0.75 mm² to 50 mm², and for multi-core conductors from 0.75 mm² to 35 mm². A lockout mechanism prevents accidental tripping, enhancing operational safety. Manufactured in RAL 7035 color, it blends seamlessly with most electrical distribution boards.
