Primax shields motor-driven appliances in residential and light commercial applications by preventing electrical power surges, including lightning, from entering the main electrical service panel. 

Primax is UL Listed for installation before the main disconnect as a Surge Arrester or after the main disconnect as a Transient Voltage Surge Arrester.

The single-point ground provides a convenient, easy access, common grounding point for signal line (cable TV and telephone) primary protectors.


The two LED lights indicate protection status.  The audible alarm alerts you when protection is disrupted.

The Panamax warranty covers lightning damage during the warranty period. (* see www.panamax.com)

Major household appliances are covered against surge damage for 3 years when a Primax is installed by a qualified electrician.

If the Primax surge protector is damaged, for any reason, during the first 5 years of ownership, Panamax will replace it free of charge!
