Multiquip EE63491 Contactor Assembly 112 kW 24V No VCR DCA400

The Multiquip EE63491 is a genuine OEM Contactor Assembly 112 kW 24V No VCR designed for the DCA400 ultra-silent diesel generator. As a direct Multiquip OEM component, EE63491 is built to the exact electrical specifications required for safe and dependable load-switching performance on the DCA400. Sourcing the correct contactor assembly is critical on a high-output generator of this class — an incorrect or substandard unit can compromise voltage regulation and output reliability. DHS Equipment supplies this part as an authorized Multiquip OEM replacement so you can restore your DCA400 to full operational spec with confidence.

Key Features

• Rated for 112 kW Output — Matched to the full load capacity of the DCA400, ensuring the contactor can handle the generator's maximum rated current without thermal overload or contact degradation.
• 24V Control Circuit Compatibility — Operates on the DCA400's 24-volt DC control system, providing the correct coil energization voltage for reliable pull-in and drop-out operation.
• No VCR Configuration — Supplied in the No VCR (no voltage-controlled relay) configuration, matching the specific electrical architecture of the DCA400 unit this part is intended for.
• Direct OEM Fitment for DCA400 — Engineered specifically for the Multiquip DCA400 ultra-silent generator, allowing straightforward installation without electrical re-termination or bracket modification.
• Genuine Multiquip OEM Part — Sourced directly through Multiquip's OEM supply chain, ensuring contact material grade, coil resistance, and mechanical actuation force all meet the original design specification for this generator model.
• Protects Generator Output Integrity — A correctly functioning contactor maintains clean load engagement and disconnection; a worn or failing unit can cause arcing, voltage instability, or failure to transfer load — keeping your generator offline when it's needed most.

The contactor assembly is the primary electromechanical switching device responsible for connecting and disconnecting the generator's output to the load circuit. On a high-capacity unit like the DCA400, the contactor must handle significant current levels repeatedly and reliably — it closes to energize the load and opens to safely interrupt the circuit during shutdown or fault conditions. When a contactor wears out, symptoms include failure to close under load, excessive arcing at the contacts, or intermittent loss of output power, all of which can disrupt operations and risk damage to connected equipment.
