Function

The Siemens 3RT7036-1AH00 functions as a relay for high-current applications. When the 48 VAC coil is energized, it generates a magnetic field that pulls the movable contacts into position, closing the circuit and allowing power to flow to the connected load. When the coil is de-energized, springs return the contacts to their open position, interrupting the circuit. This makes it a crucial component for starting, stopping, and reversing motors, as well as for controlling other industrial loads safely and efficiently from a low-power control signal.
