General
WCM8 series moulded case circuit breaker (MCCB for
short) is one of updated type MCCBs researched and
developed by the company by using advanced design
and manufacture technology internationally. The rated
insualted voltage is 800V (500V for WCM1-63).
It applies for infrequent switch of the line of AC 50Hz,
rated operation voltage 690V and below (400V for
WCM1-63), 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 damage. The MCCB is classified into four types
individually as Type C (low breaking), Type L (standard),
Type M (higher breaking), Type H (very high breaking)
according to the rated ultimate short circuit breaking
capacity (Icu) ranking. The MCCB is small in 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 verticall (vertical mounting), and horizontally
(horizontal mounting).
