The kind of load isolation switch has 3 poles, 4 poles (3 poles + on and off neutral pole)
Current
40A, 63A, 80A, 100A, 125A, 160A, 200A, 250A, 315A, 400A, 500A, 630A, 1000A, 1250A, 1600A, 2000A, 2500A, 3150A
Operation mode
Direct operation: the handle is installed directly in the middle of the switch.
Operation outside the board: the handle is installed outside the door of distributing board.

Features of SPB Manual Load Isolation Switch
1. The operating mechanism is an acceleration mechanism featuring spring energy storage and instant release, which realizes the rapid making and breaking (13.8m/s), having no relationship with the speed of the operating handle, and increasing greatly the capability of extinguishing electric arc.
2. The shell made of unsaturated polyester resin reinforced by fiberglass provides great flame resistant performance, impact resistant performance, dielectric performance and safe operation.
3. Parallel double breakpoint contact possesses self-cleaning functions.
4. All the contact materials are copper alloy plated with silver, with two separation contact surfaces.
5. Large distance of insulation.
6. Be on "0" position, the switch handle can be locked with three locks at the same time and thus avoid error operation.
