Hardwired maintenance bypass PDU designed to sit ahead of an Eaton 3 kVA UPS so the UPS can be removed or serviced without interrupting the connected load. The manual bypass switch transfers load between UPS and utility feed, and hardwired terminals suit permanent installation in a rack or wall-mount enclosure. Typical application is protecting servers, network equipment, and other 24/7 critical loads where planned UPS maintenance must not cause downtime.
