Frequently Asked Questions

What is the SIEMENS 3RA23178XB301AP6 reversing contactor used for?

The SIEMENS 3RA23178XB301AP6 is a reversing IEC magnetic contactor used to control the forward and reverse rotation of three-phase motors in industrial applications such as conveyors, pumps, and hoists. It switches motor direction by interchanging two of the three supply phases.

What are the specifications of the SIEMENS 3RA23178XB301AP6 contactor?

This SIEMENS reversing contactor has 3 poles and 3 normally open (NO) contacts, rated for 12 A with a 240V AC coil. It does not include integrated surge suppression. The manufacturer part number is 3RA23178XB301AP6.

Where to buy the SIEMENS 3RA23178XB301AP6 contactor worldwide?

You can source the SIEMENS 3RA23178XB301AP6 reversing contactor through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring the component reaches your facility reliably.

How to select a reversing contactor like the SIEMENS 3RA23178XB301AP6?

When selecting a reversing contactor, match the rated current (12 A) and coil voltage (240V AC) to your motor's full-load current and control circuit. Ensure the contactor has mechanical and electrical interlocking to prevent both contactors from closing simultaneously. The SIEMENS 3RA23178XB301AP6 meets these requirements for reversing applications.
