Normal working and installation conditions

The FSGL load isolation switch can operate reliably under the following conditions:
◆ Altitude not exceeding 2000 meters;
◆ The ambient temperature shall not be higher than 40 ℃, not lower than -5 ℃, and the relative humidity shall not exceed 95%;
◆ No explosive hazardous medium environment;
◆ No rain or snow invading the environment;
Note: If expected to be used under conditions where the ambient air temperature is above+40 ℃ or below -5 ℃ to -45 ℃, the user should explain to the manufacturer.

63-3150A load isolation switch

The load isolation switch is divided into 7 specifications from 63 to 3150A, which is a modular design basic type with three poles and four poles (three poles+neutral pole that can be turned on or off). It is mainly used for circuit connection and disconnection or for electrical purposes
Isolation, only electrical isolation is required for 1000A and above.
There is a marking window on the front to indicate the on/off status of the contacts.
According to the needs, a rear observation window can be provided to directly observe the on/off status of the contacts. The window style can be found in the operating load isolation switch behind the 160A~1600A/H cabinet.
Can be equipped with two sets of auxiliary contacts.
◆ Cable insulation cover can be configured.

63~100A load isolation switch

63A~100A is suitable for making and breaking circuits or electrical isolation.
63A~100A have three poles and four poles (three poles+neutral pole that can be turned on or off).
Two sets of auxiliary contacts can be installed as needed.
◆ Side cabinet inside and outside operations can be provided as needed.

160-1600A side operating load isolation switch

1600-1600A is suitable for making and breaking circuits or electrical isolation, with three or four poles (three poles+neutral pole that can be made or broken). 1000A and above are only suitable for electrical isolation.
◆ Products related to observation windows can be provided as needed to directly observe the on/off status of the contacts.
◆ Operation method:
Direct operation: The handle is installed on the right side of the switch.
Outside cabinet operation: The handle is installed outside the distribution cabinet door.
Two sets of auxiliary contacts can be installed as needed.
◆ The extended shaft is used for operations outside the cabinet.
The electrical performance and mechanical performance are the same as those of 160-1600A.
◆ Can be equipped with cable insulation covers.
