AC Circuit protectors
Residual current circuit breaker 4P 40 A 300 mA 3F typ A Noark
Manufacturer: Noark Electric
INDEX: 108214
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 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.
