Outstanding Features Make You Stand Out

We play extreme caution to quality and utmost attention to detail, which makes our products so perfect.

Modularization of Functional Unit

The main circuit unit and running product are coherent in interchangeability.
Strong Versatility

The operating mechanism can be separated from the whole circuit breaker for convenient and easy maintenance and fix.
Low Maintenance

No need of adjustment of driving unit; long-acting lubricating, reliable corrosion resistance, and high mechanical stability make low maintenance possible.
Long-acting Lubricating

We apply German lubricating grease boasting lower starting torsion, stronger anti-aging and oxidation resistance.
Strong Corrosion Resistance

Utilizing zinc-nickel alloy plating line with a German process to make sure our corrosion resistance is 5 to 7 times stronger than ordinary zinc-plating process.
Strong Expandability

This product can easily realize diverse arrangements and combinations to meet functions like expandability and control.
