1.The switch employs a spring-stored energy,instant-releasemechanism for accelerated opening and closing,along with a paralleldouble-breakpoint contact structure,significantly improving the electricaland mechanical performance of the switch.
2.The switch is made of glass fiber-reinforced unsaturated polyestermolding material and a manual operating handle,providing high dielectricperformance,protective capability,and reliable operational safety.
3.The switch is available in both 3-pole and 4-pole configurations(3-pole with optional switchable neutral pole).
4.There is a marking window on the front face of the switch,indicatingthe open and closed status of the contacts.A rear observation window canbe provided as needed for direct monitoring of the contact status frombehind,ensuring reliable and safe switch operation.
5.The operating handle can be directly mounted on the switch(referred to as “in-cabinet operation”)or operated from outside the distribution cabinet by extending the shaft (referred to as “external cabinetoperation”),providing convenience in operation.
6.Auxiliary normally open (NO)and normally closed (NC)contacts canbe provided as required,along with dedicated mounting bases and front andrear panel wiring methods,to meet various user needs.
7.When in the “0”position,two to three locks can be used to secure thehandle to prevent accidental operation.
