To ensure long-term reliable operation of Moulded Case Circuit Breakers (MCCBs), follow strict maintenance protocols: Before work, disconnect power and verify de-energization while wearing insulated gear. Inspect housing for cracks and discoloration regularly, check and tighten wiring terminals in accordance with standard torque requirements. Operate the switch handle repeatedly to ensure flexible opening, closing and tripping reset function. Regularly check insulation performance and contact status, keep the product surface clean and dry, and conduct routine inspection and maintenance every half year or one year according to indoor and outdoor environmental conditions.
