Schneider Electric's Square D 9055NO-120-R Magnetic Current Relay is a Class 9055, dashpot-type relay with a normally open (NO) contact and a 120 V AC control coil. Designed for motor overload protection and control applications, energizing the 120 V coil closes the NO contact to signal downstream equipment or interlock circuits. This device is part of Square D's legacy 9055 family of magnetic relays used in industrial control panels, with historical documentation describing 120 V AC coil variants and their coil terminations.
