General Information
Electrical Diagram
®
The Bourns Model 1420 Series is a DC power Surge Protective
Device (SPD) designed to protect power systems operating up
to 1200 Vdc. The unique hybrid MOV/GDT design provides an
enhanced level of protection against the effects of direct or
indirect lightning.
