Applications |
|
• GSM1 range of Moulded Case Circuit Breakers is used to distribute electric energy and to
non-frequent switch circuitry and start motor. |
• Four-pole MCCB is mainly applied in architectural electric systems to protect against overload
and short circuit for wire and cable. It can also achieve disconnection of neutral line together
with phase line to ensure safety of maintainer and operator. | |
