Keep connected equipment online when the power grid misbehaves. Eaton’s IsoBar 4 Ultra is built for environments where a basic strip is not enough, delivering 2,200 joules of surge suppression across four outlets. That higher protection rating helps absorb damaging transients before they reach servers, networking gear, AV components, or workstation electronics. The compact four-outlet layout is well suited to premium desktop installs, small rack shelves, and point-of-use protection for high-value devices. For teams that have already invested in reliable infrastructure, this model adds a stronger layer of defense against lightning-induced surges and everyday electrical noise that can shorten component life. Choose this unit when the cost of a power event is measured in lost time, damaged hardware, or service disruption. It is a straightforward, purpose-built protection device for systems that deserve more than commodity surge strips.
