3RA2434-8XE32-1NB3 SIEMENS

The 3RA2434-8XE32-1NB3 Siemens contactor assembly is specifically designed for star-delta (wye-delta) starting applications, providing a reduced voltage start to limit inrush current and mechanical stress on motors. This assembly is equipped with I/O-Link communication capabilities, enabling seamless integration into automated systems for enhanced monitoring and control. It is rated for AC-3 duty, handling motor loads of 22 kW at 400 V and 30 kW at 400 V, making it suitable for medium-sized industrial motors. The contactor operates on a 20-33 V AC/DC control voltage, offering flexibility in power supply options. Featuring a 3-pole configuration, it ensures reliable switching of three-phase power. The size S2 designation indicates its compact design, optimizing space utilization within control panels. Screw terminals provide secure and robust electrical connections. An integrated electrical and mechanical interlock enhances safety by preventing simultaneous closure of the main and delta contactors. Furthermore, it includes 3 normally open (NO) and 3 normally closed (NC) auxiliary contacts, expanding its control and signaling capabilities.
