Residual current device P 304 4P 25 A 100 mA Type A, TX3 series 411774

Protection and Safety in Your Electrical Installation

This four-pole residual current device (RCD) from Legrand’s TX³ series, rated at 25A and with 100mA sensitivity (Type A), is a critical component ensuring safety in your installation. Designed to protect people and equipment against electric shock, as well as the consequences of short circuits and overloads, its DIN-rail mounting is fast and intuitive—ideal for both professional electricians and DIY users.

Functionality and Technical Specifications

The P304 circuit breaker features high reliability and compatibility with auxiliary devices such as auxiliary contacts and overvoltage trip units. Its rated impulse voltage withstand of 4kV and high short-circuit current resistance (0.25kA) ensure stable operation even under demanding conditions. With a width of 4 modules, it enables efficient use of space in distribution boards. Manufactured from high-quality materials and marked with RAL 7035, it delivers an aesthetic appearance and long-term durability.

This circuit breaker has a rated current of 25A, making it ideal for protecting circuits with medium power consumption. Its 100mA residual current sensitivity ensures effective protection against indirect contact shocks. Designed as Type A, it detects both alternating (AC) and pulsating DC leakage currents—essential for modern electronic devices. With a short-circuit breaking capacity of 10kA, it guarantees safe disconnection in the event of a fault. The IP20 protection rating guards against finger contact and ingress of solid objects larger than 12.5mm. Additionally, an integrated lock prevents accidental re-energizing after tripping due to RCD activation, enhancing safety during maintenance. The wide operating temperature range (-25°C to +60°C) ensures reliable performance in diverse environmental conditions.

Design and Application

The P300 TX³ circuit breakers feature a thoughtfully designed construction that simplifies installation and wiring—lower entry points and shielded terminals enhance installer comfort. The test button allows regular verification of device functionality, crucial for maintaining continuous safety. This circuit breaker is suitable for electrical installations in residential, commercial, and industrial buildings where protection against electric shock and fire hazards is required. It is compatible with single-core conductors from 0.75 mm² to 50 mm² and multi-core conductors from 0.75 mm² to 35 mm².
