Circuit breaker RX3 1P B 25A 6000A 419138

Reliable protection of electrical installations – RX3 circuit breaker

This single-pole circuit breaker from the RX3 series by Legrand is a key element ensuring safety in every electrical installation. Designed to protect circuits against overloads and short circuits, it performs well in both residential and commercial buildings. Characteristic B makes it ideal for circuits with devices with high inrush current, such as motors or transformers – it allows it to react more slowly to short current surges, minimizing the risk of unnecessary disconnection.

Functionality and installation

The RX3 circuit breaker is characterized by a compact design and the possibility of flush mounting, which makes it easier to aesthetically fit into the interior. A width of 1 module allows for efficient use of space in the distribution board. Rated current of 25A and short-circuit breaking capacity of 6kA (at 230V and 400V) guarantee effective protection of the installation under typical operating conditions. The degree of protection IP20 provides basic protection against contact and ingress of solid objects.

Safety and compliance with standards

The circuit breaker meets the requirements of EN 60898 standard, which confirms its reliability and safety of use. Rated impulse withstand voltage at 4kV provides resistance to overvoltage. Made of high-quality materials, the RX3 circuit breaker is durable and resistant to mechanical damage. The energy limitation class is 3, which means it is designed to limit the effects of short circuits in installations with medium impact energy. Additionally, the rated insulation voltage Ui is 500V, which increases the safety margin.
