Abb af140-30-11-11 3-pole Contactor 130A 24VDC

Product Description

The ABB af140-30-11-11 is a 3-pole industrial contactor rated at 130 amps and designed to operate on a 24 VDC control coil. Contactors of this type serve as the primary switching device in motor control circuits, HVAC equipment, and heavy electrical distribution systems. The unit opens and closes high-current load circuits under the command of a low-voltage control signal, protecting downstream equipment and allowing automated or remote switching. Licensed electricians and industrial controls technicians are the typical installers for this class of device.

The af140-30-11-11 is suited for motor starters, HVAC compressor circuits, pump panels, and other three-phase or single-phase load applications that demand a high-current switching solution. The 24 VDC coil voltage makes it compatible with low-voltage DC control systems and PLCs commonly used in commercial and industrial automation. The inclusion of one normally open and one normally closed auxiliary contact supports interlocking and status-monitoring functions in control panels.

Key Features

• 3-pole configuration handles three-phase and single-phase high-current loads
• 130-amp continuous current rating for heavy-duty motor and compressor circuits
• 24 VDC operating coil compatible with low-voltage DC control systems and PLCs
• One normally open (NO) and one normally closed (NC) auxiliary contact for interlocking and monitoring
• DIN rail and panel-mount capable for flexible installation in motor control centers and enclosures

Compatibility

Designed as an OEM-style replacement or direct-fit contactor for 3-pole motor control and load-switching applications requiring a 130-amp, 24 VDC coil device.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NFPA 70 (NEC) requirements for motor control and switching equipment. De-energize and lock out all power sources before removing an existing contactor or installing this unit. Verify that the control circuit voltage matches the 24 VDC coil rating before energizing. Auxiliary contact wiring should be routed and terminated per the panel schematic to ensure correct interlock operation.
