T Electrically Isolated Heatsinking
T Compression Bonded Elements
T Metal Baseplate
T Low Thermal Impedance
for Improved Current Capability
Benefits:
T No Additional Insulation
Components Required
T Easy Installation
T No Clamping Components
Required
T Reduce Engineering Time
Applications:
T Transfer Switches
T AC Welders
T Motor Soft Starters
