A new fact facts flier on Photovoltaic applications for disconnect switches is now available. This informative 2 page guide provides the details specifiers need to select a disconnect switch for UL rated applications or an IEC rated applications:
- String Disconnects/Field Combiner Boxes - disconnect switch on each string of PV installed
- Combiner Boxes - add fuses to disconnects for overcurrent protection on each sub-array
- Inverter Disconnects - disconnect for the AC or DC sides
- Tracking System Motor Disconnects - An outdoor rated enclosed disconnect within sight of the motor
- Main Electrical Panels/Switchboards/Switchgear - Fusible disconnects applied as the main power disconnect method
UL & IEC Ratings:
| Application | # of poles | Standards Rating | Amps | DC Voltage |
| UL 250 VDC | 2 | UL98 | 200A - 600A | 250 |
