Shape Introduction
FAQs
Q: What is the difference between 1P, 2P, 3P, and 4P switches?
A: 1P switches control one wire, usually for single - phase circuits. 2P switches control two wires, often used for single - phase with neutral. 3P is for three - phase without neutral, and 4P is for three - phase with neutral.
Q: Can these switches be used in a high - humidity environment?
A: For the fuse switch disconnector, the relative humidity should not exceed 50% at 40°C. In lower temperatures, it can be up to 90%. Modular switches have a wide operating range, but proper ventilation is recommended in high - humidity areas.
Q: How often should I check the fuses in the fuse switch disconnector?
A: It is advisable to check the fuses regularly, especially after any electrical fault or abnormal operation. Visually inspect for blown fuses, and replace them if necessary.
