●WSX11 intelligent type with temperature of the surrounding medium is-40C~+80C

●The product is used in non-explosive hazardous media,and the media does not have enough to corrode metals and destroy insulating gases and conductive dust.

●In places where there is rain protection and no water vapor.

●The installation category is Class lll.

●The pollution level is level 3.

●The basic installation of the circuit breaker is vertical or horizontal.

●The incoming line is either the up line or the down line.

●Circuit breakers can be divided into fixed and plug-in types.
