Residual Current Circuit Breakers Ex9CL (Old version)

Modular residual current devices Ex9CL-H and Ex9CL-N in two or four-pole design. Technology is based on the classical principle of permanent magnet and electromagnetic armature, providing full voltage independence of protective functions. Circuit breakers comply with the requirements of the standards IEC/EN 61008-1.

The Ex9CL-H series provides residual current devices with conditional short-circuit resistance of 10 kA. Basic types in AC and A versions are available for nominal currents ranging from 25 to 63 A; S and S+A versions provide up to 100A. Nominal residual currents cover the values of 30, 100 and 300 mA.

The basic Ex9CL-N series of residual current device are offered with conditioned short-circuit resistance of 6 kA. Basic AC types are available in two and four-pole design, with nominal residual current of 30 or 300 mA.
