Overview
The Eaton Cutler-Hammer APF120N01 is a transient voltage surge suppressor (TVSS) engineered to protect sensitive electrical and electronic equipment from damaging transient disturbances. These devices help reduce costly downtime and protect sensitive electronic equipment against the damaging effects of transients caused by lightning, utility switching, internal load switching and more. The APF120N01 uses advanced metal oxide varistor (MOV) technology to effectively suppress voltage surges and spikes, ensuring safe and reliable operation of critical systems.
