Shunt Trip Unit Compatible Molded Case Breakers

As a reliable manufacturer in China, DZ47 Air-Switch Circuit Breaker is one of PUGAO (Plannter Electric)'s products, designed for single-phase AC power system with automatic disconnection, overload protection, short circuit protection and isolation. When the current exceeds the set rated value, the circuit breaker will automatically trip to stop the abnormal current from continuing to flow, thus protecting the electrical equipment and lines from damage.

Our AC Overload and Short Molded Case Circuit Breaker, produced by Pugao(Plannter Electric), are engineered to meet advanced requirements in power distribution protection. A key performance parameter is their ultimate short-circuit breaking capacity (Icu), typically rated between 50kA and 100kA across different models. This high breaking capacity guarantees safe interruption and system stability under severe short-circuit conditions. We are here to assist and will reply to your messages as soon as possible.
