3RA2120-1KD24-0AP0 SIEMENS

The 3RA2120-1KD24-0AP0 from Siemens is a fuseless load feeder designed for direct-on-line starting of motors at 400 V AC. This compact and efficient device is a Size S0, suitable for motor currents ranging from 9.00 to 12.5 A. It features a 230 V AC coil for reliable contactor operation. The load feeder is equipped with screw terminals, facilitating easy installation on 60 mm busbar systems. It is engineered to meet both Type of Coordination 1 and Type of Coordination 2 standards, ensuring enhanced protection and minimizing downtime in the event of a short circuit. With a high short-circuit breaking capacity of Iq = 150 kA, it provides robust protection against fault currents. The integrated contactor includes 1 NO (normally open) and 1 NC (normally closed) auxiliary contacts for versatile control and monitoring capabilities. This load feeder combines overload protection, short-circuit protection, and motor control functions in a single, space-saving unit, simplifying motor starter design and installation. Its robust design and compliance with international standards make it suitable for a wide range of industrial applications.
