One of the following four statements is inaccurate; please indicate it: ( ). A. Circuit breakers of the universal type consist of a frame structure with insulating pads and the components used, all of which form a single unit; they come in various structural forms and are designed for different purposes. B. Circuit breakers with plastic enclosures, also known as molded-case circuit breakers, have an enclosure made of molded insulating material, which combines all the components into one unit. C. Insert-type circuit breakers generally have three positions: connection, testing, and isolation. D. Drawer-type circuit breakers are a type of insert-type circuit breaker. There is a dedicated circuit breaker support mechanism during insertion; even when the insertion contacts are in a separated position, this mechanism can hold the circuit breaker in place and maintain a safe isolation distance. A drawer-type circuit breaker should generally have three positions: connection, testing, and isolation. C

One of the following four statements is inaccurate; please point it out: (D). A. Moulded case circuit breakers consist of a frame structure with insulating pads and the components used, forming a single unit; they come in various structural forms and are designed for different purposes. B. Plastic-clad circuit breakers, also known as moulded case circuit breakers, have a casing made of moulded insulating material, which combines all the components into one unit. C. Insert-type circuit breakers generally have three positions: connection, testing, and isolation. D. Drawer-type circuit breakers are a type of insert-type circuit breaker. There is a dedicated circuit breaker support mechanism during insertion; even when the insertion contacts are in a separated position, this mechanism can hold the circuit breaker in place and maintain a safe isolation distance.

D. Drawer-type circuit breakers are a type of plug-in circuit breaker. There is a dedicated circuit breaker support mechanism during insertion; even when the insertion contacts are in a separated position, this mechanism can hold the circuit breaker in place and maintain a safe isolation distance. Drawer-type circuit breakers should generally have three positions: connection, testing, and isolation; I’ve never heard of any other ones
