3RA2338-8XB30-1AC2 SIEMENS

The 3RA2338-8XB30-1AC2 is a pre-wired and tested reversing contactor assembly from Siemens, designed for efficient and reliable motor control. This assembly is rated for AC-3 duty, making it suitable for standard applications such as starting, stopping, and reversing three-phase motors. It has a power rating of 37 kW at 400 V, making it appropriate for medium-sized industrial motors. The control voltage is 24 V AC at 50/60 Hz, ensuring compatibility with common control circuits. The contactor assembly features a 3-pole configuration, providing complete control over the three phases of the motor. It is size S2, indicating its physical dimensions and current carrying capacity within the Siemens contactor range. Screw terminals are used for electrical connections, offering a robust and secure wiring method. An electrical and mechanical interlock is included to prevent simultaneous activation of forward and reverse contactors, enhancing safety and preventing short circuits. Furthermore, the assembly incorporates two normally open (2 NO) auxiliary contacts for signaling and control purposes, expanding its integration capabilities within a control system. This pre-assembled reversing contactor simplifies installation and reduces wiring time, making it a convenient solution for motor control applications.
