Product Q&A

Q:What is the difference between 3P and 4P molded case circuit breakers?

3P breakers control three live wires (L1, L2, L3) for three-phase three-wire circuits and balanced loads. 4P breakers add a neutral wire, suitable for three-phase four-wire circuits and systems requiring neutral wire current prevention.

Q:What are the precautions for wiring 3P molded case circuit breakers?

Strictly connect three-phase live wires according to L1, L2, L3 marks to ensure correct phase sequence. Use copper wires or bars with cross-sectional areas matching the rated current to ensure good contact and avoid heating.

Q:What causes inconsistent tripping of the three phases?

Common reasons include tripping mechanism failure (worn/stuck springs or locks) and poor contact of contacts (oxidation, ablation, or loose wiring). Check and replace damaged parts or clean/tighten contacts.

Q:What product tests are conducted before leaving the factory?

We conduct electrical performance testing, mechanical performance testing, appearance inspection, and temperature rise tests.

Q:How are the molded case circuit breakers packaged?

We use carton packaging, cardboard box packaging, and wooden box packaging, all complying with international export standards.
