HGL系列负荷隔离开关
  适用于交流50Hz、交流额定电压660V及以下、直流额定电压440V及以下，额定电流至3150A。在工业企业配电设备中，可供不频繁手动接通和分断电路及隔离电源用。1000A及以上仅作隔离电源，不能带负载分断电路。本产品符合IEC60947-3 GB14048.3标准。隔离开关广泛适用于建筑、电力、石油化工及其它行业的配电系统和自动化系统。
　 模块化设计结构，具有灵活多样的组合性，采用玻璃纤维增强不饱合聚脂树脂制造外壳，有很高的介电性能，防护能力和可靠的操作安全性。 
　 操作机构是弹簧蓄能、瞬时释放的加速机构，瞬时接通与分断双断点触头结构。与操作手柄的速度无关，极大提高了各项电气性能与机械性能。 
　 多种结构与操作方式，有直接观察触头通断状态的窗口，有柜内、柜外操作，有正面、侧面操作，有板后接线。
