Residual current device P 302 2P 63 A 30 mA Type A DX3 series 411556

Protection and Safety in Your Electrical Installation

The residual current circuit breaker (RCCB) P 302 2P 63A 30mA Type A from the DX3 series is a critical component for safeguarding electrical installations against the consequences of earth faults and electric shocks. Manufactured by the renowned company Legrand, this device ensures protection for both users and electrical equipment. Its primary function is to rapidly detect current differences in the circuit and disconnect power during faults, minimizing risks to life and property.

Functionality and Application

The residual current circuit breaker (RCCB) P 302 is designed for use in circuits with a rated voltage of 230V AC and a rated current of 63A. Its sensitivity to residual current is 30mA, meaning it responds to very small leakage currents, providing a high level of protection. Type A indicates its ability to detect both alternating and pulsating direct currents, making it a universal solution for most residential and commercial applications. Installation is performed on a DIN rail, facilitating seamless integration with existing electrical infrastructure. Equipped with a mechanical lock, it prevents accidental re-energizing after tripping due to a fault.

Design and Technical Specifications

The device features a compact design—occupying only 2 modules on the DIN rail—allowing for space savings in the distribution panel. Its housing is made of high-quality plastic (gray color RAL 7035), ensuring durability and resistance to mechanical damage. The connected conductor cross-section ranges from 0.75 mm² to 50 mm² for single-core cables and from 0.75 mm² to 35 mm² for multi-core cables. The short-circuit withstand capacity (Icw) is 10kA, guaranteeing reliable operation even under high surge conditions. The device has an IP20 protection rating, providing protection against finger contact and solid objects larger than 12.5mm in diameter. The operating ambient temperature range is from -25°C to +60°C.
