## Summary description

GACIA PR8NM 4P is a 4-pole residual current circuit breaker (RCCB) rated at 63 A with 30 mA residual current sensitivity, Type A. Designed to detect AC and pulsating DC leakage currents, it provides personal protection against electric shock and reduces fire risk. Suitable for residential and light commercial distribution boards requiring selective earth-fault protection.

## Long description

GACIA PR8NM 4P 63A 30mA Type A is a 4-pole residual current circuit breaker (RCCB) designed to provide sensitive earth-fault detection for multi-phase electrical installations. Rated for 63 A nominal current and 30 mA residual operating current, this Type A device detects alternating (AC) and pulsating direct (pulsating DC) leakage currents, delivering personal protection against electric shock and helping to reduce the risk of electrical fires. The compact 4-pole configuration allows integration into residential and light commercial distribution boards where selective earth-fault protection is required.
Advantages
This 4-pole RCCB offers reliable residual current detection for three-phase circuits with a neutral conductor, ensuring simultaneous disconnection of all poles to prevent dangerous touch voltages. With a 30 mA sensitivity it balances protection of people from electric shock and avoidance of unnecessary trips for small transient currents. Type A capability extends detection beyond pure AC to include pulsating DC leakage commonly produced by modern electronic loads. The device is intended for straightforward installation in standard distribution panels and maintenance procedures are simplified by the clear mechanical operation and visible trip indicator.
Suitable for
Residential distribution boards with three-phase supply and neutral
Small commercial and light industrial installations requiring earth-fault protection
Circuits supplying equipment with electronic drives, inverters or variable-speed controllers
Places where personnel protection from electric shock is required
Key specifications
Poles: 4-pole design for simultaneous disconnection of all conductors
Rated current: 63 A nominal continuous current capacity
Residual operating current: 30 mA sensitivity for personal protection
Type: Type A — detects AC and pulsating DC leakage currents
Application: Intended for installation in distribution boards for residential and light commercial use
How to use
Install the RCCB in the electrical distribution board according to local electrical codes and wiring practices, ensuring correct orientation and secure connection of all phase and neutral conductors. Verify that the device rating matches the installation load (63 A) and that the 30 mA sensitivity is appropriate for the desired level of person protection. After installation, perform an Earth-leakage test using a suitable test instrument or the built-in test push-button (if present) to confirm correct operation and trip functionality before energising the downstream circuits.
Usage recommendations
Regularly check the device operation by performing periodic trip tests and visual inspections. Avoid exposing the RCCB to excessive moisture, dust or corrosive atmospheres, and ensure that any maintenance is carried out by a qualified electrician following applicable standards and safety procedures.
