MSW Switch-Disconnectors8
The MSW line offers a range of accessories and configurations, available in the default configuration and
which can be selected to suit the application requirements. Check out below the four steps necessary
for the proper selection of the MSW switch-disconnector.
Selection
1 - Mounting
MSW switch-disconnectors are mounted on panel doors or bases according to the selected model.
g
Mounting on door: in this system, the switch-disconnector is mounted on panel doors by means of screws. The
switchdisconnector and the handle are always coupled.
g
Mounting on base: the switch-disconnector is mounted on a base, like the panel plates, by screws or DIN rail. There is a
shaft to couple the switch-disconnector to the handle. The uncoupling of the switch-disconnector and the handle is only
possible when the switch-disconnector is in the OFF position.
2 - Current
The switch-disconnector must present a rated current capacity equal to or above the rated current of the circuit/load.
The MSW switch-disconnectors withstand currents up to 160 A. The rated values are indicated in the general characteristics
table (pages 6 and 7).
3 - Handle and Shaft
The handles of the MSW switch-disconnectors, developed with IP65 degree of protection, allow the use of up to three
padlocks when in the OFF position, ensuring safety during maintenance.
For switch-disconnectors with base mounting, besides the handle, it is necessary to use a shaft.
The shaft must have a length equal to or longer than the distance between the switch-disconnector and the handle.
The handles for the MSW switch-disconnectors are available in blue and yellow or black and gray.
With those characteristics, it is possible to define a standard switch-disconnector, but WEG offers other accessories that may
be required for each application.
