M7Ⅰ-125、250Moulded Case Circuit Breaker

Applictions

The M7Ⅰ series moulded case circuit breaker applies to breaking and making operation in
AC 50/60Hz, rated operation voltage 690V or less and rated current up to 1600A circuit. It can
distribute electric energy in circuit, work as the overload of wiring and power supply equipment,
or as the protector of short circuit and under voltage. Additionally, this breaker can switch line and
start motor infrequently. The other characters of the products are: small size, large contact spacing,
high capability of break-make, and short arcing distance, this performance is better than that of
CM1 series. Therefore, it is the new product replacing the older generations of home products-
DZ10, DZ20 and M7Ⅰ series moulded case breakers, this performance is as well as ABB. S series
circuit breaker.
The product complies with the standards of IECEN60947-2, GB 14048.2-2001.
