Residual Current Circuit Breaker (RCCB) P304 4P 25A 300mA Type AC TX3 411727

### Safety and protection in your electrical installation

The RCD P304 is a key element ensuring the safety of using the electrical installation, protecting both people and devices. The use of this four-pole (4P) switch with a rated current of 25A and a differential current of 300mA (0.3A) minimizes the risk of electric shock and prevents fires resulting from insulation damage or short circuits. Designed for AC type, it effectively reacts to alternating leakage currents, making it an ideal solution for a wide range of applications.

Construction and installation – simplicity for professionals and users

The P304 switch is designed for easy mounting on a DIN rail, which significantly speeds up installation. Compact dimensions (installation depth 44 mm and width 4 modules) allow for optimal use of space in the distribution box. Terminal covers and the lower latch facilitate the connection of wires with a cross-section from 0.75 mm² to 50 mm² (solid) and from 0.75 mm² to 35 mm² (stranded). Additionally, the mechanical lock ensures stability and prevents accidental disconnection of the switch.

Functionality and parameters – reliability in operation

This residual current device is characterized by high resistance to external conditions, allowing it to operate in temperatures from -25°C to 60°C. The rated insulation voltage Ui is 500V, and the rated impulse withstand voltage Uimp is 4kV, which guarantees its reliability even in the event of overvoltages. Short-circuit strength at the level of 10kA (Icw) and surge current withstand of 0.25kA provide effective protection of the circuit against the effects of short circuits. The RAL 7035 (grey) color ensures an aesthetic appearance and easy identification in the distribution box. The ability to cooperate with auxiliary devices, such as auxiliary contacts or signaling devices, further expands the functionality of the switch.
