Circuit breaker RX3 3P C 25A 6000A 419237

Solid electrical installation protection – RX3 circuit breaker

This three-pole circuit breaker from Legrand’s RX3 series is a key element of any safe electrical installation. Designed to protect against the effects of overloads and short circuits, it provides reliable operation in both residential and commercial buildings. Characteristic C makes it ideal for circuits with devices generating short-term inrush currents, such as motors or transformers – it allows it to react more slowly to short current surges, therefore tolerating the starting of devices with a motor well.

Functionality and technical parameters

The RX3 circuit breaker with a rated current of 25A and a short-circuit breaking capacity of 6kA (according to IEC 60947-2 at 400V and EN 60898 at 400V) effectively protects the circuit from damage. Mounting on a TH35 rail is quick and intuitive, and the compact dimensions (width 3 modules, embedding depth 44 mm) allow for optimal use of space in the distribution box. The IP20 degree of protection provides basic protection against contact and the ingress of solid objects. The rated voltage of 400V guarantees compatibility with most standard installations.

The short-circuit breaking capacity is high, amounting to 6kA (at 400V) and 10kA (at 230V), which ensures effective protection in the event of a short circuit. Characteristic C is ideal for circuits with receivers generating inrush currents. Mounting on a TH35 rail is a standard solution that facilitates installation. The compact width of 3 modules saves space in the distribution box, and the rated voltage of 400V guarantees compatibility with most installations. The IP20 degree of protection provides basic protection against contact and the ingress of solid objects.

Safety and compliance with standards

The circuit breaker meets the requirements of EN 60898 and IEC 60947-2 standards, which confirms its high quality and reliability. Made of high-quality materials, resistant to temperature and weather conditions, it ensures long-lasting and trouble-free operation. The black operating lever makes it easier to identify the circuit breaker in the distribution box and allows for sealing, preventing accidental switching on or off of the device. The rated impulse withstand voltage Uimp is as high as 4kV, which further increases safety.
