HGL 3/4P Load Isolation Switch

The HGL  Load Isolation Switch provides reliable circuit isolation for  systems, supporting 63A-3150A loads with 750-1000V insulation and 6-12kV impulse withstand. Designed for industrial applications, this isolation switch operates at AC400-660V/50Hz across AC-21/22/23 utilization categories, featuring 10Ie making capacity and short-time withstand currents up to 50kA. With 5000-cycle mechanical endurance and compact 3P/4P designs (0.32-49kg), the HGL  switch ensures safe maintenance and load control. Its robust construction includes 3000-3500V dielectric strength and low operating torque (3.5-60N·m), making it ideal for renewable energy and power distribution systems.
