Schneider Electric 9055-NO116 Industrial Magnetic Relay

The Square D (Schneider Electric) 9055-NO116 Magnetic Relay is a Class 9055 dashpot magnetic relay designed for instantaneous current sensing and switching in industrial control circuits. It provides motor overload protection and current monitoring in AC and DC systems, and is commonly installed in motor control centers, switchgear, industrial control panels, conveyors, pumps, and heavy manufacturing equipment requiring magnetic current relay protection. Maintenance technicians and system integrators rely on this relay for equipment repair, retrofit, expansion, and replacement to maintain reliable current monitoring and protective control functions. The 9055-NO116 is a dashpot-type unit that trips instantly when the preset current threshold is reached and supports automatic reset (hand reset optional). It accepts up to 600 VAC or 250 VDC, with a continuous contact rating of 10 A and a maximum pilot duty of 750 VA at 600 VAC and 100 VA at 250 VDC. The standard configuration is SPST Normally Closed, with Normally Open available as Form Y44, and it mounts on a panel for convenient integration in AC or DC industrial control circuits such as motor starters, conveyors, pumps, compressors, and machine tools. This relay belongs to the Class 9055 dashpot magnetic relay family, and common replacements include Square D 9055-NO117, 9055-NO118, and 9055-NO119 for retrofit or expansion projects.
