3000,4000,6000A Manual high current knife switchDetailed product description：

Scope of application
3000,4000,6000A manual high current knife switch is suitable for use in power lines with AC 50Hz, voltage up to 1000V, DC 1200V, and rated working current of 6000A and below. It is used for no-load operation and power isolation.

structural characteristics
The knife switch adopts dual blades distributed on both sides of the static contact, locked with leaf springs and screws. When a short circuit occurs in the power grid, the electromagnetic locking force between the two parallel blades and the spring plate compensates for the contact repulsion, thereby achieving high electric stability
Sex.
The conductive components of the knife switch are fixed on the base with an insulation board made of fiberglass pressed plastic, which has high insulation strength and mechanical strength. The pull rod made of fiberglass pressed plastic has high mechanical strength, thus ensuring the mechanical life of the knife switch.
