2018 High quality thermal magnetic circuit breaker - DAM3-630 MCCB Molded Case Circuit Breaker – DaDa Detail:
Overview
The rated current of DAM3-630 molded case circuit breaker can reach up to 630A. These electrical devices are suitable for the protection of power distribution circuits with an alternating current of 50-60Hz and a rated operating current up to 1000A. They can also be used in electric motors for infrequent starting and overload protection as well as protection against short circuiting and undervoltage conditions.
The circuit breakers feature the characteristics of small volume, high breaking capacity, and short flashover during operation.
