3RA1345-8XB30-1AC2 SIEMENS

The 3RA1345-8XB30-1AC2 is a reversing contactor assembly from Siemens, designed for AC-3 applications. It is suitable for switching three-phase motors with a power rating of 37 kW at 400 V. This assembly comprises two contactors that are mechanically and electrically interlocked to prevent simultaneous closure, ensuring safe reversing operations. The size S3 contactors are equipped with screw terminals for secure and reliable electrical connections. The control voltage for the contactors is 24 V AC, operating at 50/60 Hz. This reversing contactor assembly is ideal for applications requiring frequent motor reversals, such as in conveyor systems, machine tools, and other industrial machinery. Its robust design and reliable performance make it a suitable choice for demanding industrial environments. The electrical interlock enhances safety by preventing short circuits that could occur if both contactors were energized at the same time. The mechanical interlock provides an additional layer of protection, ensuring that only one contactor can be engaged at any given moment. This assembly simplifies the wiring and installation process compared to using individual contactors and interlocks.
