7specifications of HGL load isolation switch from 63A to 3150A: Basic model of modularized design, possesses three poles, and fourpoles (3 poles+on and off neutral pole). It is suitable for electric isolation. Switches over 1000A are only suitable for electric isolation.
Mark winkow is set in the front side to indicate the on andoff state of the contact.
Rear observation window can be provided according to the demand to observe directy the on and off state of the contact,
For window pattern ,refer to the back operational load isolation switch, HGL-160A-1600A/H.
Two sets of auxiliary contacts can be assembled according to demand.
The electric cable insulating cover can be assembled.
HGL Z2-160A/4JF11-380V In 125AChange over load isolation switch, inlet, AC rated voltage 380v, Anventional thermal current 160A;rate current 125A,4 poles, operation outside the board, auxiliary NO+NC
160A-3150A is stuitable for the making and breaking of electriacl isolation circuit or electric insulation. Those over In 1000A are only suitable for electric isolation.
160A-3150A possesses three poles and four poles (3 oples+on-off beutral pole).
Observation window for prodrcts below 630A can be provided according to the demand to observe directly the on and off state of contact.
Two sets of auxiliary contacts can be assembled according to demand.
Mechanical property and electric property correspond to the mechanical property and electric property of HGL-160A-31500A.
1.The elastic-accumulating accelerating mechanism for instant release realizes the rapid making and breaking(13.8m/s),having nc relationship with the speed of the operating handle, and increasing greatly the capability of extingushing electric arc
2. The shell made of unsaturated polyester resin reinforced by glass fibre possesses excellent performance of flame resistant, dielectic performance, safe operation, resist carbonic performance and resist impact performance.
3. Parallel double gap contact possesses self cleaning functions.4. All the contact materials are copper alloy plated with silver, and possess two separation contact surfaces.
5.Large insulation distance6.Be on "O", the products can lock the handle with three locks at the same time and thus can avoid error operation.
HGL series load isolation switch mainly suitable for AC 50Hz. rated voltage to 660V. DC rated voltage up to 440V, rated current up to 3150A, The switch is used in the infrequent making and breaking circuit.
Operation
Direct operation: The handie is instaled directly inthe middle of the switch. Operation outside the board:
The handle is installed outside the door off distrbuting board.
