Structural features

● High rated short circuit breaking capacity.

● Dual wiring function with easy connection of standard busbars and flexible hard conductors at the outlet.

● With red and green safety indicators for greater safety.

● Products can be used with a wide range of modular accessories, such as SD OF MV MN MX.

● The plastic parts such as the housing are made of highly flame retardant, high temperature and impact resistant plastic.

● Applicable working conditions and working environment:

a. Ambient temperature: Ambient temperature -5°C to +40°C. When the ambient temperature is not the reference 30°C, the current value is corrected by referring to the coefficients in Table 10.

b. Current correction factors used at different altitudes

c. Mounting method: Mounting with TH35-7.5 steel mounting rails.

With isolation function, it can be used as an isolation switch when disconnecting lines for line and equipment maintenance.
