Residual current circuit breaker 4P 40 A 300 mA 6 kA 3F typ A Noark

The Ex9L residual current circuit breakers are designed for domestic and industrial applications. Type A residual-current circuit breaker is sensitive to residual sinusoidal current and pulsating direct current. Modular residual-current protections of the Ex9CL-H and Ex9CL-N series are available as 2 and 4-pole protections. The technology is based on the classic principle of permanent magnet and polarized relay, offering full independence of protective functions from voltage. Types AC, A, G, G+A, S, and S+A are available for rated currents from 16 to 63 A. Rated differential currents are available for the values of 10, 30, 100, 300, and 500 mA. The switches meet the requirements of IEC/EN 61008-1.

The 6kA version of Ex9L-N residual current devices is mainly intended for less demanding applications, such as basic protection in domestic installations. The basic Ex9L-H series provides residual-current protection with 10 kA short-circuit strength. The Ex9L-N series provides residual-current protection with 6 kA short-circuit strength.
