Professional Molded Case Circuit Breaker Supplier

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.

The Pugao AC 4 Pole Molded Case Circuit Breaker 225A conforms to, and in many aspects surpasses, the requirements of relevant international and national standards for its critical specifications, such as rated operational voltage, rated insulation voltage, and ingress protection rating (e.g., IP40).All certified key performance data are legibly marked on the unit itself and are fully detailed in the accompanying technical manual. We also maintain full type test reports from accredited authoritative bodies and welcome you to examine these reports for verification at any time.We are convinced that transparency with technical data is the foundation of trust. For further information or to request the test reports, please do not hesitate to contact us.

Here at Pugao(Plannter Electric), our core belief is that electrical safety shouldn't be a luxury—it's the bedrock of a secure and comfortable life. Consider our 100A, 4P Electronic Trip Unit: we use high-quality thermosetting plastic for the casing, which is injection-molded under high heat and pressure. This advanced manufacturing process provides outstanding dimensional stability, enhanced insulation strength, and consistent arc resistance, giving you confidence in your electrical infrastructure.
