Multiquip 7431861113 Voltage Change Over Board - OEM Generator Replacement Part

The voltage change-over board is a critical electrical component that enables voltage configuration switching in high-output generators, allowing operators to select between multiple three-phase (208V, 220V, 240V, 416V, 440V, 480V) and single-phase (120V, 127V, 139V, 240V, 254V, 277V) voltage outputs to match specific load requirements. This OEM board is engineered for the demanding conditions of 600 kVA super silent generators, managing power distribution across revolving field synchronous generator systems operating at 1,800 rpm and 60 Hz frequency.

During installation or replacement, proper torque specifications are critical for safe operation—the voltage change-over board tie bolts must be torqued to precisely 1088.6 lbf∙in (123.0 N∙m) according to Multiquip technical specifications. This component works in conjunction with the generator's star-connected armature configuration and OCR/main circuit breaker protection systems to ensure reliable voltage delivery across all output terminals.

Compatible generator models include:

• DCA600SSV (WhisperWatt Series)
• DCA600SSV4F3
• DCA600SSV4F3B
• DCA600SSV4F3PB
