Low load switch, also known as switch fuse suitable for AC power frequency circuits manually infrequently off-load circuit can also be used to line overload and short circuit protection through load switch power off Route touch knife complete schematic overload and short circuit protection by Fuse completed before the 1970s used the plastic cover and steel knife switch low voltage load switch switch belong to the small capacity of the low pressure switch contact load switching speed and handle operation speed of the larger capacity of low-voltage load switch operating mechanism with spring Principle of operation of the switching speed and handle the speed of the storage structure is relatively simple movement speed has nothing to do along with reliable mechanical interlock switch is not closing the lid open and closing the lid can not be opened after the switch ensures safety switch has a breaking load long life capacity secure frequent operation of small compact size and light weight require little maintenance, and other advantages of breaking rated current overload current can short-circuit breaking current and prevent equipment missing running ability switch has visible isolation fracture equipped with about the binding capacity of the ground switch electric spring mechanism can remote remote control.
