3 Product Overview
The PEDH series isolation switch is developed and designed by Projoy Electric Co., Ltd. using the modular concept. The switch
body is assembled with special modules and new appearance design which reduces the exposed metal parts of the switch
body and improves the safe operation performance; the modular design facilitates the disassembly and combination of the
switch, and is suitable for different use requirements and occasions; It adopts two operation modes: handle operation mecha-
nism and electric energy storage, which is convenient for the reliable operation of the switch.
PEDH series Molded Case DC Switch is suitable for low-voltage DC distribution network with rated working voltage of DC1000V,
DC1500V and rated working current of 160A~500A, which can meet the corresponding rated current of on-load making and
breaking, and can also withstand the overload current in the line in a short time.
PEDH series isolation switch can be used for main power switches, isolation maintenance switches and emergency stop
switches in new energy industries, energy storage systems, photovoltaic systems, electric power, building construction and
petrochemical factories.

1) Visualization window: The opening and closing positions of the moving contacts are clearly visible, providing a higher level
of safety assurance;
2) "0" position padlock: at zero position, the handle can be padlocked to prevent misoperation;
3) Rotating double breakpoint contact structure: ensure the isolation safety distance and meet the needs of reliable isolation;
4) Double-spring operating mechanism: Double-spring energy storage mechanism realizes quick connection and discon-
nection the transition effect is independent of the operation speed.
Safe isolation
1) It can be operated with load;
2) Modular structure design: The product is composed of a single-pole module and an operating mechanism module. The
operating mechanism can provide various positions to improve the utilization of installation space;
3) Operation mode: Provide a variety of operation modes, such as operation in the front cabinet, operation outside the front
cabinet, side operation, etc.;
4) Bracket installation: The bracket can be installed horizontally or vertically to better adapt to on-site installation occasions.
