PA & PB Series Panel Protection Devices
Sentrex
®
PA and PB Series surge protection devices
protect your sensitive electronic equipment from
external or internal transient activity. Units can be
customized with remote monitoring, noise filtration and
flush mount options.
All PA and PB units are approved for indoor or outdoor
use and feature all-mode protection. Units provide
excellent protection when placed at branch panels or at
specific pieces of equipment. They can also suppress
external surges when mounted at the main service panel.
Also, the PA120T and PB120T are ideal for installation
in residences to protect the entire home infrastructure,
including expensive home appliances and home theater
equipment.
Meets UL1449
Third Edition
PA & PB Series provide
surge protection at the
main service panel, sub panel
or at sensitive equipment.
