|For the switching of 600VAC-800VAC circuits, large contactors have traditionally been the only viable option but new high capacity relays from ZETTLER are challenging those assumptions.|
The new AZSR1160 and AZSR1180 PCB mount relays from ZETTLER provide system designers with a small form-factor alternative for switching power levels up to 165kVA.
These new SPST relays can switch voltages up to 920VAC and currents up to 180A, all with a holding (coil) power of less than 0.5W. Contact gaps and insulation distances are optimized for commercial PV systems deployable up to 7000 m above sea level.
|Key Features or Design Parameters include: |
· Specially designed terminals simplify thermal management and maximize lifetime
· 3.6mm contact gap available
· >10mm clearance/creapage
· High surge breakdown voltage of 10kV· Coil voltage options from 6-48VDC
· UL and TÜV ratings
