High performance

The NOARK Ex9L-N 108369 residual current circuit breaker features an instantaneous trip time, meaning that it responds instantly to any abnormalities associated with current flow. A rated current of 25 A and a residual current of 300 mA provide effective protection against electrical shock, regardless of installation conditions.

Safety and reliability

The device provides protection in undemanding applications such as domestic installations where standard circuits are used. The circuit breaker operates selectively against other S or S+A type residual current circuit breakers, providing additional safety for the user. The product has a wide operating temperature range of -25°C to +60°C and an IP20 protection rating, making it ideal for a variety of environments.

Easy installation and testing

The switch can be installed on a TH-35 mm rail and the direction of power supply is arbitrary (from above or below), providing installation flexibility. A test button makes it easy to check the operation of the switch, which should be done regularly to ensure that the device is working properly. The product has a mechanical life of up to 20,000 switching cycles and an electrical life of up to 4,000 cycles.
