As
commercial and office equipment become more sophisticated, 20
amp circuits are required. To protect these circuits, EFI has
developed two high-performance, 20 ampere plug-in products. The
F-120-20E is a 120 volt version rated at 420 joules and includes
two NEMA 5-20 outlets. The F-220-20E is a 220 volt version rated
at 720 joules and includes one NEMA 6-20 outlet.
