Note A vertical load switch installation switches framework closing mechanism to protect steel cable jacket should not be grounded in series should be unloaded several minutes before touchdown B closing operation run all rotating parts without jamming closing after opening in place sufficient safe distance C and load switch fuse melts when used in tandem should have immediately should be made optional fault current is greater than the load switch breaking capacity to ensure the melt fuse load switch can then contact the Ministry of well-connected sub-gate closing D No overheating inspection should be careful to check out on crack dirty porcelain vase flicker switch can not be washed with water discharge phenomenon indoor low-voltage load switch is used infrequently off-load circuit; overload and short circuit protection circuit can be used. Overload and short circuit protection is done by fuses. When the current exceeds the rated current of the corresponding multiples of Xinxiang load switch, fuse to fuse the corresponding time to complete overload; theoretically instantaneous fuse short-circuit current. Suizhou Shiyan load switch load switch, load switch, the power provided by the Xi'an Huayi Huayi power plant. Xian Huayi power plant (www.xahy.com) strong, credible, in Xi'an high-voltage circuit breakers and other industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Huayi power and you hand into the brilliant, for a better future!
