FAQ

What is the coil voltage for this A9 contactor?

The coil voltage is not specified on the visible labels of the unit in the photos. Please verify the voltage required for your application. You may need to inspect the coil terminals (A1/A2) on the physical unit or contact us to check our specific inventory.

Can the CA5-40E auxiliary contact block be removed or replaced?

Yes, the CA5-40E is a standard front-mounted auxiliary contact block. It can be easily unclipped from the A9 contactor and replaced with another compatible block from the CA5 or CAL5 series to suit different signaling requirements.

Is this A9 contactor compatible with modern overload relays?

The A9 contactor is part of ABB's classic A-line series and is specifically designed to be paired with TA25DU thermal overload relays. While it might be adaptable, for guaranteed compatibility and performance, using the specified overload relay series is recommended.
