TEM3 Moulded Case Circuit Breaker
TEM3 Moulded Case Circuit Breaker

Application
TEM3 series moulded case circuit breaker is suitable for industrial or commercial power and lighting with AC 50/60Hz, rated working voltage up to AC 600V/ DC250V,
rated current up to 1200A. It's a kind of economical breaker with the characters of stable and reliable function, beautiful appearance, small size and long life. It
can be used for conversion of line and infrequent starting motor. It can also be attached to install the accessories which have protection function for avoiding
loss-voltage. Under-voltage, The product can install connection line with front board and back board, it also can be equipped hand-operating apparatus of motor-
operating apparatus to control in a remote distance.
