一、用途 APPLI
CATION
DZX24-100系列塑壳断路器(以下简称断路器)在交流50Hz,额定工作电压至415V,额定工作电流至100A及以下电路中用于照明、配电线路及电动机的
过载和短路保
护,亦可作为线路的不频繁转换,以及电动机的不频繁起动之
用。并且可配装分励脱扣器和辅助触头、报
警触头实现远距离分闸和提供辅助
信号。
DZX24-100 range plastic
cover breakers (abbr. breakers) are mainly
used in the circuit of AC frequency 50Hz,
rated operating voltage up to 415V
and rated
operating current up to 100A and below for
protection of overload
and short circuit of
lighting and distribution lines and motor, as well
as the
unfrequented changeover and
unfrequented starting of motor. This circuit
breaker can be fitted with shunt trip,
auxiliary contacts and alarming
contacts to
realize the long-distance switching-off and
provide auxiliary
signal.
