Cleaning, Maintenance And Component Inspection Of Low-voltage Pole-mounted Circuit Breakers

Removing accumulated dust, dirt, and potential corrosion products from the equipment surface can improve its heat dissipation performance and lower its operating temperature. During cleaning, special attention should be paid to smoke and metal particles within the arc-extinguishing chamber, as long-term accumulation of these substances can affect the normal operation of the Lv Pole Mounted Circuit Breakers. Simultaneously, the contact surfaces should be inspected for signs of melting, wear, etc., and contact pressure tests should be performed if necessary.
