Product Description

AC Load Break Disconnector Manufacturer

AC Load Break Disconnector switch is a type of equipment that isolates the power failure part from the live part and creates a clear break point to isolate the faulty equipment or carry out the maintenance.

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.

Product Benefits

• Quick and perfect installation every time
• Base, door or DIN rail mounted
• Installation in any direction: horizontal, vertical or even at the ceiling
• A wide variety of accessories to customize the installation,such as handles shafts, auxiliary contacts, cabling accessories and additional power poles.
• Flexibility to plan your installation
• Snap-on accessories available.
• Easy to install
• High performance

Load break switches are devices used to open an electrical circuit by isolating the source from the consumer. Whether they are manual, motorised or with a trip function, these devices ensure the on-load making, breaking and safety disconnection of low-voltage electrical circuits. Easy to assemble and easy to use, they are suitable for structures evolving in the industrial sector, public distribution, as well as emergency switching, distribution panels and motor feeders.

Safe reliable operation

• Reliable position indicator through visible windows.
• The opening and closing of the switch is fully independent from the speed of operation, ensuring safe operation under all conditions.
• High temperature withstand: no derating up to 70°C.
• Ambient Temperature: -40°C to +70°C.
