Description
The Miscellaneous Product AZ2100-1A-12DE SPST Relay E-Mech is a high-current electromechanical switching component used in a control system to enable low-voltage control of larger electrical loads in HVAC systems. It is installed inside control panels or equipment modules where a 12 VDC coil signal activates internal contacts to switch up to 40 amps of power. It isolates control circuitry from load circuits while allowing operation of compressors, motors, fans, or auxiliary systems. It operates as a power interface within electrical parts, supporting safe load switching, automated control logic, and consistent operation under repeated cycling conditions.
