HH15 Series Isolator Fuse Block

Function and Use

HH15 series isolating switch fuse assembly, QA and QP series isolating switches (hereinafter referred to as switches), switches are mainly used in power distribution circuits and motor circuits with high short-circuit current, as manual and infrequent operation main switches or total switches. They are especially suitable for installation in higher-level drawer-type low-voltage complete equipment, but are generally not used for directly switching single motors. Among them, the QA and QP series isolating switches are also not suitable for directly starting single motors.
