7.1 分励脱扣器 Shunt release
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 120VAC 的 70%-110% 之间时，能可靠分断断路器。
Power supply is connected to the shunt release according to outlet wire number (no need to
distinguish positive and negative for direct current). At rated control supply voltage of 70%-110%,
shunt release should be reliable to trip breakers.
