SGL Copper 3 Phase Change Over on/off Isolation Load Switch

Summary

A: SGL AC load isolation switch is widely used in the distribution system and automatic system of architecture, electrical power, petrochemical, and other industries. it is suitable for AC 50hz, rated voltage to 660V, DC rated voltage up to 440V, Rated current up to 3150A.

B: Many forms of structures and operations in which the on and off state of contact is abserved through windows. on off isolator switch 3 phase changeover switch 3 phase load switch break

C: There are many types of switch: operation inside or outside the board, frontal or lateral operations, there are also connections behind the board.

D: All the contact material are copper alloy plated with silver, and possess two separation contact surfaces

E: Be on “O” position, it can lock the handle with three locks at the same time and thus can avoid error operation on off isolator switch 3 phase changeover switch 3 phase load switch break
