Product Description
A Load break switch is similar in structure to a disconnector (both have visible disconnection points in the disconnection state), but it can be used to open and close circuits, which in turn resembles a circuit breaker.
However, a circuit breaker can control any circuit, while aLoad break switch can only switch on or off load current, or switch off over load current, so it is only used to switch off and on circuits under normal conditions, not short circuit fault current. However, it is required that its structure can pass the fault current of short circuit time without damage.
