8.1 欠压脱扣器
断路器带有欠压脱扣器时，应使欠电脱扣器先通电，断路器才允许合闸.
根据外挂欠电压模块上的接线端子编号接入电源(直流电源不必区分正负极)
当电源电压下降到欠压脱扣器额定工作电压的 35%～70%
范围内时，欠压脱扣器能可靠的分断断路器；当电源电压
低于欠压脱扣器额定工作电压的 35%时，欠压脱扣器能防
止断路器闭合；当电源电压高于欠压脱扣器额定工作电压
的 85%时，欠压脱扣器能保证断路器可靠闭合。
8.1Undervoltage tripper
When the breaker has an undervoltage tripper, the undervoltage tripper should be electrified, and
then the breaker allows switch on.
Power supply is accessed according to wiring connector number on
the external undervoltage module (anode and cathode of DC power supply
are not differentiated).
When power voltage declines to 35%～70% of the rated working
Voltage of undervoltage tripper, the undervoltage tripper can
reliably break the breaker up; when power voltage is lower than
the rated working voltage of undervoltage tripper by 35%, the
undervoltage tripper can prevent the breaker from closing; when
power voltage is higher than the rated working voltage of
undervoltage tripper by 85%, the undervoltage tripper can
guarantee the reliable closure of breaker.
8.2 分励脱扣器
根据引出的导线编号接入电源(直流电源不必区分正
负极)。当分励脱扣器的外加电压介于额定控制电源电压的 70%-110% 之间时，能可靠分断断路器。
8.2 Shunt tripper
Power supply is accessed according to wiring connector number on
the external undervoltage module (anode and cathode of DC power supply
are not differentiated).When impressed voltage of shunt tripper is between
70% and 110% of rated control power voltage, the breaker can be reliably
broken.
