Multiquip C25DNF315-1R 20A Contactor, 12VDC, DCA40SSKU4F

The Multiquip C25DNF315-1R is a genuine OEM 20A Contactor, 12VDC, DCA40SSKU4F designed for the DCA40SSKU4F ultra-silent diesel generator. As a factory-sourced component, this contactor meets the exact electrical specifications required by the DCA40SSKU4F, ensuring correct coil voltage, contact rating, and switching behavior. Sourced directly through Multiquip's OEM supply chain, this is the same part installed during original manufacture. If your generator is experiencing switching faults, failed load transfer, or electrical control issues, replacing the contactor with the correct C25DNF315-1R is the right first step.

Key Features

• Correct 12VDC Coil Rating — Matched to the DCA40SSKU4F's 12-volt DC control circuit, ensuring the coil energizes and releases properly under normal operating voltage.
• 20-Amp Contact Capacity — Rated at 20 amps to handle the switching loads specific to this generator's electrical control system without thermal overload or contact welding.
• Genuine OEM Component — Factory-sourced from Multiquip, this contactor carries the same part specification as the original unit, with no guesswork on compatibility.
• Direct Fitment for DCA40SSKU4F — Engineered specifically for the DCA40SSKU4F ultra-silent diesel generator, this contactor installs into the existing mounting position and connects to factory wiring without modification.
• Protects Downstream Electrical Components — A correctly functioning contactor prevents arcing, uncontrolled current flow, and damage to connected loads — a failed unit can cause broader electrical system faults in the generator panel.

A contactor is an electrically controlled switch used to open and close high-current circuits within a generator's control and power distribution system. In the DCA40SSKU4F, the 20A contactor operates on a 12VDC control signal, allowing low-voltage logic circuits to switch higher-current loads on and off reliably. When a contactor wears out or fails, the result is typically a circuit that will not energize, intermittent load dropout, or in some cases a welded contact that keeps a circuit permanently closed — all of which can disrupt generator output and damage connected equipment.
