Circuit breaker RX3 3P B 25A 6000A 419171

Overcurrent protection switch RX3 – reliable protection of electrical installations

The RX3 3P B 25A overcurrent protection switch is a key element in protecting electrical installations from the effects of overloads and short circuits. Designed for both domestic and commercial applications, it ensures safe and reliable operation of electrical devices. Its construction based on characteristic B makes it ideal for circuits with devices with high inrush current, such as motors or transformers.

Features and application

This three-pole (3P) switch with a rated current of 25A is characterized by a high short-circuit breaking capacity – up to 6kA at 400V and 10kA at 230V. This means that in the event of a short circuit, the switch will quickly and effectively cut off the power, minimizing the risk of damage to the installation and preventing fires. Flush mounting makes the device discreet and aesthetically integrates with the surroundings. A width of 3 modules allows for easy placement in a standard distribution box.

• Overload protection: Protects the circuit from overload – when the drawn current exceeds the permissible value, the switch automatically switches off.
• Short-circuit protection: In the event of a short circuit, the switch immediately cuts off the power, protecting wires and devices from damage.
• Flush mounting: Allows for aesthetic and discreet placement of the switch in the wall or other structural element.
• Breaking capacity: High breaking capacity (6kA/10kA) ensures effective protection even in difficult conditions.
• Characteristic B: Ideal for protecting circuits with devices with high inrush current (e.g. motors).
• Versatility: Suitable for use in AC installations with a rated voltage of 400V.

Construction and technical parameters

The RX3 switch has been designed with durability and reliability in mind. Its solid construction and high-quality materials guarantee a long service life and trouble-free operation. The IP20 degree of protection provides protection against finger contact and against the ingress of solid objects larger than 12.5 mm into the device. Energy limitation class 3 means a high ability to suppress surge energy, which further increases the safety of the installation. The rated impulse withstand voltage Uimp is as high as 4kV, which proves resistance to sudden voltage surges. The device meets the requirements of EN 60898 and IEC 60947-2 standards, which confirms its compliance with European safety standards.
