Product Overview
FR series auxiliary switches are one of the supporting components for high-voltage complete sets of equipment. Their appearance is beautiful and compact, and the thickness of each section of the switch is only 6.5mm, which is about half of the thickness of each section of the usual auxiliary switches, reducing the installation space of the switch, and they are suitable for controlling various high-voltage switching operating mechanisms such as closing, breaking, interlocking, signaling circuits, and can also be used as change-over or combination switches, and they are also more suitable for use in the GIS combination electric apparatus. It is also suitable for use as a changeover or combination switch, and is more suitable for use in GIS combination electric apparatus and other actuators with a small internal space.
