              Both moulded case circuit breakers and isolating circuit breakers deal with electricity all the year round. Electricity is a double-edged sword, and it is easy to hurt people if it is not used well. In order to reduce the occurrence of accidents and everyone's safety, we still need to let everyone know the matters needing attention in the installation and maintenance of MCCB.
              Moulded case circuit breaker is mainly used to distribute electric energy and protect lines and power supply equipment from overload, short circuit, undervoltage and other faults. Attention should be paid to the following items during installation, operation and maintenance.
              (1) Before installation, check whether the parameters on the nameplate are consistent with the actual needs, and fix the circuit breaker on the installation plate vertically.
              (2) When wiring in front of the board, select the wire with the corresponding cross-sectional area, peel off the insulating outer layer with an appropriate length, insert it into the hole of the wire hoop, and press the outer layer of the wire hoop tightly to wrap the wire. Then, screw the connecting hole of the clamp and the circuit breaker terminal. When connecting the copper bar, the wiring board should be fixed on the circuit breaker first, and then fixed with the copper bar. The wiring behind the Board shall be fixed on the wiring board in strict accordance with the requirements of the instructions.
              (3) Before the circuit breaker is put into operation, it is necessary to carefully check whether the fixed connection part is firm, and ensure that the operating mechanism is in a flexible state.
              (4) The circuit breaker has been confirmed to be accurate when leaving the factory. It can be adjusted at will when it is in use. In case of overload or short-circuit fault, the circuit breaker shall remove the fault before closing.
              (5) The circuit breaker shall be inspected periodically during use. The transmission part shall be lubricated regularly. Meanwhile, the dust of the shell shall be removed, and the metal particles and black soot on the wall and side pieces of the arc extinguishing chamber shall be eliminated.
