Separated Switch

Separated Switch

GSG2 range separated switch is more commonly known as isolation switch or disconnector. It is designed for infrequent connecting, breaking, and isolation of an AC 50Hz 690V or DC 440V electrical circuit in power distribution system and motor systems. Its rated working current is up to 1600A. The product is widely used in the power transmission, power distribution as well as automation systems for industries such as building, electrical, petroleum, and chemicals.

Structural Features and Standards
1. With modular structure design, the isolation switch can be flexibily combined with other functional modules. Meanwhile, its exterior housing is made using unsaturated polyester resin and is then reinforced using glass fibre. So, the housing comes with good dielectric properties and superior resistance to fire, carbonization and impact, and can well protect the interior elements of the switch.
2. The parallel connected contacts with dual-breaking point have self cleaning function. All contacts are made of silver-plated copper alloy.
3. The product comforms to IEC60947-1, IEC60947-3, GB/T14048.1 and GB14048.3 standards.
