Characteristics of Products
1.The
elastic-accumulating accelerating mechanism for instantaneous release realizes
the rapid on and off (50km/h),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 grassfire
possesses excellent performance of flame resistant, dielectric performance, and
safe operation.
3.Parallel double bread contact compact possesses self-cleaning functions.
4.All the contact materials are copper alloy plated with silver , and possess
two separation contact surfaces.
5.Large clearance of insulation
6.The products can lock the handle with three locks at the same time and thus
can avoid error operation.
7.It can assure the circuit to be turned on and off under load, and has reliable
over-current and short -circuit protection function.
