Multiquip 6888153542 Relay DCA-10SPX4 60Hz Gen - OEM Replacement Part

This relay controls critical electrical functions in Multiquip's WhisperWatt super silent generator series, managing power distribution within the open-delta excitation system. The relay works in conjunction with the voltage regulator to maintain stable power output across the A, B, C, and D connections of the open delta winding during steady state loads. When this relay fails, generators may experience voltage irregularities, failure to maintain excitation, or complete shutdown of the electrical system.

Designed for use with Kubota D1503-M diesel engine-equipped generators rated at 18.4 hp @ 1,800 rpm, this relay is engineered to handle the demanding conditions of telecom sites, lighting facilities, and industrial construction applications. The component plays a vital role in the state-of-the-art open-delta excitation system, which consists of electrically independent windings among the stationary windings of the AC output section.

Compatible with the following Multiquip generator models:

• DCA10SPX4
• DCA10SPXU4
• DCA15SPXU4F
• DLW-400ESA4/DLW-400ESA4F
• DLW330X2
