Residual Current Circuit Breaker RX3 4P 25A 30mA TYPE AC 402062

Residual Current Device RX3 – Safety and Reliability in Your Installation

The RX3 4P 25A 30mA Type AC residual current device is a key element in protecting electrical installations, both in residential and commercial buildings. It provides protection for people against electric shock and protects the installation against the effects of short circuits and overloads. This four-pole switch, with a rated current of 25A and a sensitivity of 30mA, effectively detects leakage currents to earth, minimizing the risk of hazards.

Functionality and Technical Parameters

The RX3 switch is characterized by high reliability and durability. Its construction based on proven Legrand technology guarantees stable operation even in difficult conditions. DIN rail TH35 mounting simplifies installation and integration with the existing distribution board. The rated short-circuit breaking capacity of 10kA provides effective protection in the event of short-circuit currents. The locking mechanism prevents accidental disconnection of the device, increasing safety.

This switch is characterized by a rated current suitable for most standard electrical circuits (25A), a fast response to leakage currents thanks to a sensitivity of 30mA, and the ability to detect both sinusoidal and pulsating alternating currents (Type AC). It is designed to protect three-phase or multi-phase circuits (4 poles). Its high resistance to short-circuit currents (breaking capacity 10kA) ensures long-term reliability. Compact dimensions (width of 4 modules, i.e. 71.2 mm) allow for efficient use of space in the distribution board. The device can operate in a wide range of ambient temperatures (-25°C to +60°C) and has an IP20 degree of protection, protecting against contact with fingers and solid objects with a diameter greater than 12.5 mm.

Application and Benefits

The RX3 residual current device is used to protect lighting circuits, socket outlets and electrical appliances exposed to moisture or insulation damage. Its installation is required by law in many countries to ensure the safety of users and compliance with standards.
