VW3GZ-16 DC Disconnect switch
- The VW3GZ series supports a wide power range with a rated current from 200A to 4000A and a maximum working voltage of DC 1500V for main circuit isolation.
- It ensures extreme safety in high-capacity systems by providing a high short-time withstand current of up to Icw 1s = 100kA.
- The switch body is constructed from high-strength DMC (Dough Molding Compound) to provide superior impact resistance and excellent insulation properties.
- The advanced dual-stage main-arc contact structure uses customized anti-welding materials to significantly enhance electrical service life.
- Reliable power distribution is guaranteed through a reinforced internal mechanism and a high-performance motorized motor design.
- Every unit is manufactured in strict compliance with the latest EU RoHS directives to support sustainable and eco-friendly development.
