Square D 2936S1C27A U Electromechanical Relay

Square D 2936S1C27A U is a 120 V coil electromechanical relay coil from Schneider Electric’s Square D 2936 family. This coil is the control element that, when energized, actuates the relay’s internal contacts to open or close a circuit, enabling a low-voltage control signal to drive higher-power loads in industrial control panels. The 2936S1C27A U designation identifies a specific coil variant within the 2936 family, intended to be used with compatible Square D contact assemblies in control schemes that require a 120 V coil. Typical applications include motor control circuits, sequencing and interlocking in automation panels, and HVAC control systems where reliable relay actuation of auxiliary circuits is required. Install and operate in accordance with the Square D/Schneider Electric guidelines and applicable electrical standards, ensuring the coil voltage matches the system supply to prevent coil burnout and ensure proper relay operation.
