Product Description

| Rated frequency | 50/60Hz |
| Material | Copper |
| Rated Voltage | 400V |
| Pole | 3P 4P |
The Knife Transfer Switch is designed for power lines with AC 50Hz and a voltage up to 1000V, or DC 1200V. It can handle a rated working current of6000A or below, providing uninterrupted operation and isolation of the power supply.
This knife switch features double blades distributed on both sides of the static contact, which are secured with leaf springs and screws. In the event of a short circuit in the power grid, the electromagnetic locking force created by two parallel blades and spring sheet compensates for contact repulsion, resulting in improved electrical stability.
The conductive parts of the knife switch are attached to the base using an insulating bottom plate made of glass fiber pressed plastic, which offers high insulation strength and mechanical strength.Additionally, the pull rod is also made of glass fiber pressed plastic, ensuring a long mechanical life for the knife switch.
