Overview
Siemens 3MT8120-1AC27 is a robust, heavy-duty AC-3 contactor designed for industrial motor control applications, built within the substantial Size S6 frame. Rated for a continuous operational current of 120A at 400V, it is capable of reliably switching three-phase motors up to 55 kW, making it suitable for high-power equipment such as large pumps, compressors, and conveyor systems. This contactor complies with IEC 60947-4-1 standards, ensuring excellent electrical insulation up to 690V and high surge impulse resistance, which provides dependable operation in demanding industrial environments. It features a three-pole main contact block with durable screw-type terminals, engineered to withstand heavy-current conductors and vibrations typically encountered in industrial settings. Auxiliary contacts, generally configured as multiple normally open and normally closed contacts, enable integration with control and signaling circuits.
