• The elasticaccumulating accelerating mechanism for instant release realize the rapid making and breaking (13.8m/s), having no relationship with the speed of the operating handle,and increasing greatly the capability ofextinguishing electric arc.
• The sheu made of unsaturated polyester resin reinforced by glass fiber possesses excellent performance of flame resistant, dialectic performance, safe operation, resist carbonic performance and resist impact performance.
• Parallel double gap contact possesses self cleaning functions.
• All the contact materials are copper alloy plated with silver, and possess two separation contact surfaces.
• Large clearance of insulation.
• Be on "0", the products can lock the handle with three locks at the same time and thus can avoid error operation.
