APC SURGEARREST PMG3XS-B 480/277 V 120 kA/PH | Panel Mount, Enterprise

Keep high-value equipment online when the electrical environment turns unpredictable. APC SURGEARREST PANELMOUNT is built for 480/277 V installations that need serious surge handling, with 120 kA per phase capacity designed for demanding distribution points and upstream protection roles. This is the kind of protection specified when downtime is expensive and the load behind the panel matters. By absorbing large transient events before they reach downstream equipment, it helps reduce the risk of controller faults, power supply damage, and avoidable service interruptions. The panel-mount format supports clean integration into electrical infrastructure where space, access, and serviceability all matter. For facilities, industrial rooms, and other high-exposure power paths, this model is positioned above basic strip-style protection. It is intended for environments where surge tolerance, installation discipline, and system continuity are part of the design requirement—not afterthoughts. When the cost of a failure is measured in lost operations, this level of protection earns its place.
