## Summary description

Legrand residual-current circuit breaker (RCCB) P304 TX3, 4-pole, rated 40 A with 0.1 A (100 mA) residual current sensitivity, Type A. Designed to detect and disconnect earth leakage including pulsating DC components, it provides protection against electric shock and fire risk in three-phase installations. Suitable for industrial and residential distribution boards requiring selective residual-current protection.

## Long description

Legrand residual-current circuit breaker P304 TX3 4P 40A 0.1A Type A is a four-pole device for detecting and disconnecting hazardous earth leakage currents in three-phase electrical installations. Designed to respond to both AC and pulsating DC leakage components, this Type A RCCB provides selective residual-current protection at a rated current of 40 A and a trip sensitivity of 0.1 A (100 mA). It is intended for use in distribution boards where discrimination between upstream and downstream protections and reliable disconnection of leakage currents are required.
Advantages
The device detects AC and pulsating DC leakage currents and trips at a defined residual current level to reduce the risk of electric shock and fire. Its four-pole design enables simultaneous isolation of all phases and neutral in three-phase systems, supporting safer maintenance and clearer fault resolution. The breaker’s compact format and DIN-rail mounting compatibility simplify installation in residential and industrial distribution panels.
Suitable for
 Three-phase distribution boards in residential, commercial and light-industrial settings
 Protection of circuits with electronic equipment that can create pulsating DC leakage (Type A requirement)
 Applications requiring selective or coordinated residual-current protection with upstream devices
 Situations where simultaneous disconnection of phases and neutral is preferred
Key specifications
 Number of poles: 4P (phases + neutral)
 Rated current: 40 A
 Residual operating current (sensitivity): 0.1 A (100 mA)
 Tripping characteristic: Type A — responds to AC and pulsating DC residual currents
 Intended application: three-phase TN, TT and similar distribution systems
 Mounting: DIN-rail compatible enclosure dimensions for distribution panels
How to use
Install the four-pole residual-current breaker in the distribution board according to applicable electrical codes and manufacturer mounting orientation. Connect the three phase conductors and neutral to the respective terminals and ensure secure tightening to the specified torque. Wire the supply and load sides so the device monitors residual current for the protected circuits. Test the device after installation using an appropriate testing procedure or instrument to verify correct trip function at leakage currents near the rated sensitivity.
Usage recommendations
Use this Type A residual-current breaker where electronic loads may produce pulsating DC leakage; coordinate with upstream protections to achieve selective fault clearance and follow local regulations for earth-leakage protection. Periodically test the device and inspect connections during maintenance to ensure continued reliable operation.
