Product Description
The difference between load break switch and circuit breakers?
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.
Because the arc extinguishing device and contact of the Load break switch are designed to cut off and connect the load current, the Load break switch should be used with the fuse in most cases, and the latter is responsible for cutting off the short-circuit fault current.
The opening and closing frequency and operating life of load disconnecting switches are usually higher than those of circuit breakers.
