CD4B series molded case circuit breaker electric operating mechanismDetailed product description：

CD4B electric operating mechanism is a specialized mechanism suitable for local or remote electric operation of 100-1600A electronic and intelligent molded case circuit breakers, which can achieve remote or centralized control of various electrical equipment.
functional structure
Ultra small, about 1/3 lower in height than CD4 type
Driven by a permanent magnet DC motor and powered by a switching power supply, it has low power consumption and a wide voltage range
Complete voltage specifications, compatible with both AC and DC
Lifespan of 20000 times, closing or opening time of 1s~1.5s
The length is shortened by about 1/3 compared to CD2B type, which can make room for the parameter adjustment panel of electronic molded case circuit breakers
Can add a safety padlock
Can be compatible with various electronic molded case circuit breakers ranging from 100 to 1600A both domestically and internationally
