MGR series isolating switch fuse groupDetailed product description：

Product Overview:
The MGR series isolation switch fuse group (hereinafter referred to as the switch) is a multi pole, manually operated switch made of glass fiber reinforced unsaturated polyester resin with a high dielectric performance, protection capability, and reliable operational safety.

The operating mechanism is a spring-loaded, instantaneous release acceleration mechanism with a multi break contact structure for instantaneous connection and disconnection. Regardless of the speed of the joystick, it greatly improves various electrical and mechanical performance.
The isolation switch fuse group can ensure the connection and disconnection of the circuit with load, and has reliable safety breaking protection against overcurrent or short circuit.
Clearly visible disconnected state.
Has strong resistance to moisture and heat.
The switch has a beautiful, novel, simple, small size, and comprehensive functions.

Application of MGR series isolating switch fuse group products

The MGR series isolation switch fuse group is mainly used for AC 50Hz, rated voltage 660V, DC rated voltage 440V, and rated current up to 630A. It is used for infrequent connection and disconnection of circuits.

Product Features
1. The acceleration mechanism with instantaneous release of spring energy storage achieves fast connection or disconnection (13.8 meters/second), independent of the speed of the operating handle,
Greatly improved the ability to extinguish arcs.
2. The shell made of glass fiber reinforced unsaturated polyester resin has good flame retardant properties, dielectric properties, and safe operation
Complete.
3. Parallel multi breakpoint contacts have self-cleaning function.
4. It can ensure the connection or disconnection of circuits with load and has reliable overcurrent and short-circuit safety protection functions.
5. Replacing the melt is safer, more convenient, and faster.

Working and environmental conditions
The MGR isolation switch fuse group can reliably operate under the following conditions:
1. Sea level not exceeding 2000 meters;
2. The ambient temperature shall not exceed 40 ℃, not be lower than -5 ℃, and the relative humidity shall not exceed 95%;
3. Non explosive hazardous medium environment;
4. No rain or snow invasion environment;
Note: If it is expected to be used under conditions where the ambient air temperature is above+40 ℃ or below -5 ℃ to -45 ℃, the user should inform the manufacturer.
