Product structure:
ZW32 port type circuit breaker is mainly composed of solid sealed integrated pole, current transformer, spring operated mechanism, and base. The spring operating mechanism and pole are fixed on the base, and the sealing structure between the integrated sealing pole, current transformer, and spring operating mechanism is suitable for outdoor environments. It has a compact and elegant design, a simple and clear structure, easy installation, and can meet the requirements of arc extinguishing chamber opening distance and overtravel without adjustment during installation. This type of circuit breaker also reserves auxiliary switch contacts, which can fully meet the different needs of users.

Product inspection and maintenance:
1 Due to its special design structure, the circuit breaker on this
column can ensure long-term maintenance free use for users. It is
recommended that users conduct a power frequency withstand voltage
test every three years or so, and regularly clean the insulation
parts of the circuit breaker according to the local environmental
pollution level.
2 Users are not allowed to replace or use electrical components
that are inconsistent with the original model specifications at
will.
3 Operators should understand the performance, installation,
adjustment, and maintenance knowledge of the mechanism, record any
problems encountered during operation, and notify the manufacturer
if necessary.
