Residual current device P 302 2P 63 A 30 mA type F (HPI) DX3 series 411592

Safety and protection with Legrand DX³ residual current circuit breaker

This two-pole residual current circuit breaker from Legrand’s DX³ series provides reliable protection for electrical installations against the effects of short circuits and electric shocks. Designed for use in 230V circuits, it ensures protection for both users and connected equipment. Its compact design (2 modules) allows for easy installation in distribution boards, saving valuable space.

The circuit breaker features a rated current of 63A and a sensitivity of 30mA, making it an ideal solution for protecting circuits with higher power demand. Type F ensures effective protection against both alternating and direct leakage currents, including disturbances generated by modern electronic devices. This is especially critical in installations containing electronically powered equipment such as computers or chargers.

Functionality and installation

The circuit breaker is mounted on a DIN rail, the standard in most electrical distribution boards. The mechanism lock prevents accidental switching on or off, enhancing operational safety. The test button enables regular verification of the circuit breaker’s proper functioning, which is essential for maintaining continuous protection.

This RCD is compatible with DX³ series accessories such as auxiliary contacts and signaling devices, allowing for expansion of the protection system’s functionality. The ability to add optional components provides flexibility to tailor the system to specific installation requirements. With a short-circuit withstand rating of 10kA, it guarantees reliable operation even during severe electrical network disturbances.

Design features and compliance with standards

Constructed from high-quality materials, the Legrand DX³ circuit breaker ensures long-term, fault-free operation. The housing color (RAL 7035) blends seamlessly into the distribution board environment. It complies with the IEC/EN 61008-1 standard, confirming its adherence to European safety requirements. The rated impulse withstand voltage Uimp is 4kV, and the rated insulation voltage Ui is 250V — these parameters demonstrate high resistance to overvoltages and insulation damage.
