## Summary description

Legrand P304 residual-current circuit breaker (RCD) 4-pole, rated current 63 A, residual operating current 0.3 A (300 mA), Type AC. Designed to detect and disconnect AC leakage currents to protect people and installations from electric shock and fire risk. Suitable for three-phase distribution boards, industrial or commercial electrical circuits requiring earth-fault protection.

## Long description

Legrand P304 residual-current circuit breaker 4P 63A 0.3A Type AC is a four-pole protective device designed to detect AC earth leakage currents and interrupt supply to limit electric shock and reduce fire risk. Intended for three-phase distribution boards and industrial or commercial electrical installations, this RCD responds to alternating residual currents and provides a fast disconnection for fault currents at a rated operational current of 63 A and a sensitivity of 0.3 A (300 mA).
Advantages
This 4-pole RCD offers selective earth-fault protection for three-phase systems while keeping a compact footprint for panel installation. Its Type AC characteristic ensures reliable detection of sinusoidal alternating leakage currents. With a 63 A rated current it is suitable for higher-load circuits, and the 300 mA sensitivity provides effective protection against earth-faults that can cause fire or equipment damage. The device is engineered for compatibility with common rail mounting systems and standard distribution board layouts.
Suitable for
 Three-phase distribution boards in commercial and industrial premises
 Circuits requiring high-rated residual-current protection (up to 63 A)
 Protection against AC-type leakage currents in installations without DC components
 Applications where fire-risk mitigation from earth faults is required
Key specifications
 Poles: 4 (four-pole)
 Rated current: 63 A
 Residual operating current (sensitivity): 0.3 A (300 mA)
 Tripping characteristic: Type AC (responds to AC sinusoidal leakage)
 Intended mounting: panel/rail mounting for distribution boards
How to use
Install the RCD in the distribution board according to local electrical codes and mount it on the appropriate DIN rail or panel slot. Connect the three phase conductors and neutral to the input and output terminals following the correct polarity and torque recommendations from installation standards. Verify that upstream overcurrent protection and downstream circuits match the rated current and characteristics of the device. After wiring, perform insulation and operation tests, including a functional trip test at commissioning and periodic checks in service.
Usage recommendations
Use this Type AC residual-current breaker where detection of pure AC leakage is required; avoid installations with significant DC components or pulsed leakage currents without confirming compatibility. Regularly test the device during routine maintenance to ensure reliable operation and coordinate it with upstream and downstream protective devices to maintain selectivity.
