Function

The Siemens 3RT2036-1AB04 motor contactor is primarily used for switching electrical loads, particularly 3-phase AC motors. When the 24V AC control voltage is applied to the coil, the main contacts close, connecting the motor to the power supply. The integrated 2 NO + 2 NC auxiliary contacts provide reliable feedback and control signals for interlocking, signaling, and sequence control circuits, making it a crucial component in motor starters, control systems, and automation applications.
