ZETTLER Introduced High-Capacity PCB Mount Solar Relays Optimized for 690VAC Grid Inverters
For the switching of 600VAC-800VAC grid inverters circuits, large contractors have traditionally been the only viable option but high-capacity relays from ZETTLER are challenging those assumptions.
The AZSR1160 and AZSR1180 high-capacity PCB mount solar relays from ZETTLER provide system designers with a small form-factor alternative for switching power levels up to 165kVA. These 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 7000m above sea level.
Key Features of Design Parameters include:
Specially designed terminals simplify thermal management and maximize lifetime
3.6mm contact gap available
>10mm clearance/creepage
High surge breakdown voltage of 10Kv
Coil voltage options from 6-48VDC
UL and TUV ratings
