Overview
Honle’s SQ-Series three-phase, electronically controlled, vacuum-interrupting distribution automation switch provides reliable, economical switching, sectionalizing, advanced metering, and automation systems for distribution circuits rated up to 38 kV.
The HL switch combines solid cycloaliphatic epoxy vacuum interrupters with a reliable, lightweight operating mechanism that utilizes a magnetic actuator to provide a lifetime of troublefree operation. The solid polymer system does not rely on a gaseous, liquid, or foam dielectric. The HL switch is highly resistant to ozone, oxygen, moisture, contamination, and ultraviolet light. Switch operations are programmed in an electronic control with accurate characteristics and a host of advanced features. When system requirements change, program settings are easily altered with no sacrifice of accuracy or consistency.
