Multiquip M4214000222 Control Box (KY) - OEM Replacement Part for Super Silent Generators

The control box assembly serves as the electrical command center for Multiquip DCA180SSJU super silent generators, housing critical voltage change-over components and control circuitry that manage generator output and operation. This control box contains the voltage change-over bus bars that allow field configuration between 208Y/120, 220Y/127, 240Y/139 and 416Y/240, 440Y/254, 480Y/277 three-phase output voltages, as well as the control and operation panel components that monitor and regulate the 144 kW prime output (158 kW standby) generator performance.

Located as a major component assembly on the DCA180SSJU4F series, this control box integrates with the generator's revolving field synchronous system operating at 1,800 rpm and 60 Hz frequency. The unit manages power factor correction at 0.8 and coordinates with auxiliary single-phase AC power systems. Proper installation and maintenance of this control box is essential for reliable generator operation, particularly when performing voltage change-over procedures that require tie bolt torque specifications of 65.0 lbf·in (14.7 N·m) on the voltage change-over board connections.

This control box is compatible with the following Multiquip generator models:

• DCA180SSJU4F3
• DCA220SSJU4F3
