General
WCM1 sereis moulded case circuit breaker (MCCB for short)
is one of new type MCCBs researched and developed by
using advanced design and manufacture technolgy internationally.
The rated insulation voltage is 800V (WCM1-63 is 500V).
It applied for infrequent switch of the line of AC 50Hz, rated
operation voltage 690V and below (WCM1-63 is 400V), and for
infrequent starting of the motor. The MCCB with overload,
short circuit and under-voltage protection fitting can protect the
line and power device from demage. The MCCB is classfied
into four types individually as Type C (low breaking), Type
L (standard), Type M (higher breaking), Type H (high breaking
according to the rated ultimate short circuit breking capacity (Icu)
ranking. The MCCB is small volume, high breaking capacity,
short flashover (zero flashover of some spare parts), and
vibration resistance, is the ideal product for using on land and at
ship. The MCCB can be installed vertically (vertical mounting)
and horizontally (horizontal mounting).
