Product Description
Always the top brands will be the most popular ones. It is my opinion that this is because of their marketing strategy, history, reputation and worldwide acceptance more than any other reasons. This does not mean they are better or worse in any way, just means they are more accepted world widely.
Here is something you have to keep in mind when choosing a load break switch manufacturer:
- Whether the contact and terminal board are copper plated with silver, with two separate contact surfaces, to ensure good electrical performance and reliability of closing in place?
- Whether the operation mechanism adopts spring energy storage, instantaneous release acceleration mechanism, instantaneous connection and break double breakpoints?
- Whether there is an arc isolation plate inside the shell to separate the contacts, ensure that the arc in each phase independent indoor extinguishing, improve the safety performance of the switch?
- Except the wiring part, whether the product adopts fully closed design, with a window to directly observe the on-off state of contact?
- Whether can a special padlock be installed on the operating handle to lock the handle to prevent misoperation?
