Successful Short-Circuit Breaking Test of Q&S High-Capacity Air Circuit Breaker

Location: Ningbo, China

Q&S Electric is proud to announce the successful completion of short-circuit breaking tests for its latest high-capacity Air Circuit Breaker (ACB) model, conducted in cooperation with a certified third-party testing laboratory.

This newly developed ACB achieved a breaking capacity of 100kA at 690V, marking a significant milestone for Q&S in the field of low voltage power protection. The product underwent multiple short-circuit and overload simulations, all of which were passed with zero failure, no contact welding, and stable arc extinction.

“This is not just a technical achievement, but a signal to our global clients that Q&S is fully capable of delivering high-performance ACBs for the most demanding applications,” said Bary Zhang, Boss of Q&S Electric.
