LMGL3D series DC disconnect switches DC1000V/DC1500V
The LMGL3D series DC disconnect switches are suitable for power systems with rated voltages of DC1000V/DC1500V and below, and rated operating currents of 630A and below. These switches can be used for infrequent switching, isolating and disconnecting circuits to facilitate equipment maintenance or repair. They are widely used in various industries such as construction, power, and metallurgy.
1. Rotating double-end contact structure: Ensures safe distance of the disconnecting switch, meets reliable isolation requirements, and the contacts have a self-cleaning function.
2. Double-spring operating mechanism: The double-spring energy storage mechanism enables rapid switching, and the switching effect is not affected by the operator’s speed, improving the breaking speed.
3. Housing is made of glass fiber unsaturated polyester resin, which has excellent flame retardant properties, dielectric properties, anti-carbonization properties, and impact resistance.
4. Complies with the latest EU RoHS directive.
5. The operating mechanism supports front and side operation.
6. The arc extinguishing system adopts the arc extinguishing principle of permanent magnet raising arc voltage, improving breaking performance.
