Isolating Switches with a current capacity of 160 to 1600 Amperes are suitable for use in circuits for making and breaking connections, as well as for electrical isolation. Switches with a rated current of 1000 Amperes or more are only to be used for electrical isolation. Three-pole and four-pole (3+1) switches are available.
Switches rated 1600 Amperes or less are available with an observation window, through which the state of the contacts (open or closed) can be directly observed.
Auxiliary contacts can be fitted if required.
