Applications
IEC contactors like the ABB B9-30-10 are standard components in motor control centers (MCCs), machine tool panels, HVAC control circuits, and general industrial automation. They are used to switch three-phase and single-phase loads — typically motors, resistive loads, and lighting banks — under the command of a low-voltage control signal applied to the coil. The 110/120VAC coil voltage makes this contactor compatible with North American control circuits, and the 1NO auxiliary contact is commonly wired into indicator, interlock, or PLC feedback circuits. The B9 series from ABB Control fits into the lower end of ABB's IEC contactor range, well suited for loads up to approximately 4kW/5HP at 230V or 7.5HP at 460V in AC-3 duty. These contactors are still widely used in replacement and MRO (maintenance, repair, and operations) applications across manufacturing, process control, and building systems.
This ABB B9-30-10 Control Contactor has been inspected and appears to be in good used condition. It was pulled from a working environment where it was previously in service. The unit shows normal wear consistent with field use; the terminals and contact faces appear clean and intact in the photos. Please view our photo set and contact us if you have any questions.
