Load Isolate Switch - Low Voltage Electric Components
Introduction: Load Isolate Switch [Vacuum Circuit Breaker]MGL Series Load Isolate Switch (hereinafter refers to the switch) is developed by our company with advanced European technology. It is of international late 90s level. It is the ideal new generation product among similar ones. The switch is widely used in the power distribution and automation systems of construction, power, petrol-chemical industries and other fields. Its modular design structure enables flexible combination. The glass fiber reinforced unsaturated polyester resin shell has high dielectric properties, protection and reliable operational safety. The operation mechanism adopts the acceleration mechanism of spring energy storage and instantaneous release. It can instantaneously access and break multi-point contact and has nothing to do with the speed of the operation handle, which greatly improves the electrical and mechanical performances.
It has many structures and operation modes. For instance: there is the window from which the contact breaking state can be observed. There are inside, outside cabinet operations, frontage and side operations and back-board wiring. The switch is of pleasing appearance. It is novel, simple, small and functional. It is the best option among similar products.
MGL series products have won 3C authentication certificate.
Product Features: Load Isolate Switch [Low Voltage Electric Components]
1. The instantaneously released acceleration mechanism of spring energy storage realizes rapid access and breaking (13.8m/s) which has nothing to do with the speed of the handle and greatly enhances arc-extinguishing ability.
2. Glass Fiber reinforced unsaturated polyester resin shell has high dielectric properties and reliable operational safety.
3. Paralleled double-breakpoint contacts have self-cleaning effect.
4. All contact materials are silver plated copper alloy which has two separated contact surfaces. The isolation distance is long.
5. At “0” position, three locks can be used together to avoid misuse.
Function of Load Isolate Switch [Low Voltage Electric Components]
MGL Series Load Isolate Switch is mainly used in AC 50Hz 660V rated voltage 440V DC rated voltage and 3150A rated current. It applies to infrequent accessing and breaking the circuit as well as isolating the circuit.
