Isolators Ex9I40

Ex9I40 series installation switches are intended for a wide range of applications, especially as master switches. Their design meets all the requirements for a safe power interruption.

They are available in one up to four pole design versions. The device width always corresponds to only one module. This benefit allows their use for all applications where maximum installation space economy is of essence.

Utilisation category AC-22A allows use also for more demanding industrial applications requiring frequent switching. They are provided with an interlocking function in the OFF position.
