DZX 24-100 Range Plastic Cover Breakers
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.
二、结构特点 STRUCTURE FEATUR

产品体积小、重量轻、分断能力高,且采用模块化组合式设计,可同辅助触
头、报警触头、分励脱扣器等方便地组合使用。
