the external undervoltage module (anode and cathode of DC power supply
are not differentiated).
When power voltage declines to 70%～35% 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.
