High-Performance 63-400A Manual 3Pole Disconnector Changeover Switch Fuse Isolator

Scope of application

The CGLR (HGLR) Series Fuse Combination Switches are mainly suitable for AC circuits with a frequency of 50 Hz, a rated AC voltage up to 660 V, a rated DC voltage up to 440 V, and a rated current up to 800 A. They are designed for non-frequent switching operations of circuits.

The HGL series load isolation switch can operate reliably under the following conditions:

1. Altitude above sea level does not exceed 2,000
2. Ambient temperature is not higher than +40ºC and not lower than -5ºC;
3. Relative humidity is not greater than 95%;
4. No explosive or hazardous atmosphere;
5. No exposure to rain or snow.
6. Note: If the load isolation switch is intended for use in environments where the ambient temperature is higher than +40ºC or lower than -5ºC (down to -45ºC), customers should inform the manufacturer in advance.

Characteristics of Products

1.The elastic energy storage and instantaneous release mechanism enables fast switching operations (13.8 m/s). It is independent of the operating handle speed, thus improving various electrical performance metrics.
2.The shell, made of glass-fiber reinforced unsaturated polyester resin, features excellent fire resistance, dielectric properties and operational safety.
3.The parallel double-gap contact has a self-cleaning function.
4.It ensures reliable load switching operations for circuits, and provides dependable over-current and short-circuit protection.
5.Fuse replacement can be performed safely, conveniently and efficiently.

Product Characteristics

1. The CGLR (HGLR) Type I adopts a modular design structure.
2. Ensures reliable load switching, as well as dependable over-current and short-circuit protection with circuit breaking function.
3. The off-state is visually obvious.
4. Available in 2-pole, 3-pole, and 4-pole (3 poles + on/off neutral pole) configurations.
5. Offered in 10 rated current sizes ranging from 63 A to 400 A.

Structure and Operation Modes

1. Direct front operation: The handle is mounted on the front of the switch.
2. Direct side operation: The handle is mounted on the right side of the switch. (Users requiring left-side handle mounting shall specify this requirement in advance.)
3. Front-mounted external operation: The handle is mounted on the front of the distribution board.
4. Side-mounted external operation: The handle is mounted on the right side of the distribution board. (Users requiring left-side handle mounting shall specify this requirement in advance.)
5. Type S auxiliary contacts are available upon request.
