Product Q&A
Q:What is the difference between 3P and 4P molded case circuit breakers?
A:
3P breakers control three live wires (L1, L2, L3) for three-phase three-wire circuits. 4P breakers add a neutral wire, suitable for three-phase four-wire systems, allowing simultaneous cutoff of phase and neutral lines to prevent abnormal neutral current.
Q:What are the precautions for wiring 3P molded case circuit breakers?
A:
1. Strictly connect three-phase live wires according to L1, L2, L3 marks to ensure correct phase sequence. 2. Use copper wires or bars with cross-sectional areas matching the rated current to ensure good contact and avoid overheating.
Q:What are the reasons for inconsistent tripping of the three phases?
A:
Common reasons include: 1. Tripping mechanism failure (worn/stuck springs or locks). 2. Poor contact of contacts due to oxidation, ablation, or loose wiring. Solutions involve checking/replacing parts, cleaning contacts, or tightening wiring.
Q:What product tests are conducted before leaving the factory?
A:
We conduct comprehensive tests including electrical performance testing, mechanical performance testing, appearance inspection, and temperature rise tests to ensure product quality meets standards.
Q:How do you package the molded case circuit breakers?
A:
We use carton packaging, cardboard box packaging, and wooden box packaging, all complying with international export standards to ensure products are not damaged during transportation.
