2000A load isolation transfer switch for emergency and grid power supply
Product characteristics
1. The acceleration mechanism of instantaneous release of spring energy storage realizes fast on or off (13.8 M / s), which is independent of the speed of the operating handle and greatly improves the ability of arc extinguishing.
2. The shell made of glass fiber reinforced unsaturated polyester resin has good flame retardant, dielectric, carbonation and impact resistance.
3. The parallel double break point contact has self-cleaning function.
4. All contact materials are copper silver alloy with two separate contact surfaces.
5. Large isolation distance.
6. When it is in "0" position, three locks can be used to lock the handle at the same time to avoid misoperation.
