Types of Circuit Breaker Accessories









High-Durability Insulating Parts
Our breaker insulation parts—bushings, gaskets, that kind of stuff—are built tough. Yirong uses high-quality insulating materials and precision manufacturing. Before any breaker part leaves our factory, it goes through voltage and mechanical life tests. So even under tough loads, it still opens and closes smoothly and gives you reliable protection.
Got an older or unusual piece of equipment and can’t find ready-made parts? No worries — we also offer custom solutions. Just tell us what you need, and we’ll make it for you.
So you won’t have to worry about leaks or shorts. They fit most breakers just right, hold on tight, and help your gear stay in good shape for longer.


Highly Versatile
Our parts are made to fit a wide range of breakers. They’re built to match the original specs of VS1 series, as well as other vacuum and outdoor breakers. So when you swap them in, they fit right the first time — no extra adjustments needed. They just work. Works with indoor, outdoor, VS1 breakers, you name it. Easy to put in, easy to swap out. Speeds up your assembly line and keeps things running nice and steady.
Yes, it can be replaced separately, but after replacement, the travel and contact gap must be readjusted, and loop resistance and withstand voltage tests must be performed.
- The closing and opening circuits will be open.
- Incorrect position signals.
- False alarms in the downstream monitoring system.
- The protection system cannot interlock.
Most VS1 and ZN63 mechanisms are interchangeable, but attention must be paid to the number of contacts (number of normally open and normally closed groups) and the length of the linkage.
