Schneider Electric 9055-NO116 Industrial Magnetic Relay

Description:

The Square D 9055-NO116 Magnetic Relay is used to provide instantaneous current sensing and electrical switching for motor protection, overload detection, and industrial control circuits. Commonly installed in motor control centers, switchgear, industrial control panels, conveyor systems, pumps, and heavy manufacturing equipment requiring magnetic current relay protection. Maintenance technicians and system integrators use this relay for equipment repair, retrofit, expansion, and replacement to maintain reliable current monitoring and protective control functions.

Applications:

The Square D 9055-NO116 is a dashpot-type magnetic current relay designed to trip instantly when the preset current threshold is reached. It is suitable for both AC and DC circuits and is commonly used for motor overload protection, jam detection, and protective interlocking in industrial automation systems. The relay features automatic reset as standard and is designed for continuous-duty service in demanding industrial environments.
