Key Features

• Rated for High-Current Switching — Engineered to handle 150A continuous load switching, meeting the electrical demands of large diesel generator output circuits.
• 24VDC Coil Operation — Operates on a 24VDC control signal, matching the generator's onboard control system voltage for seamless integration.
• Genuine OEM Component — Authenticated Multiquip part built to the same specifications as the original contactor installed at the factory, ensuring correct pole configuration and contact rating.
• Direct Replacement Fitment — Confirmed for DCA400SSI4F, DCA400SSI4F3, DCA400SSI4F3B, and DCA400SSI4F3PB super-silent generator models with no adaptation required.
• Protects Generator Output Integrity — A properly functioning contactor ensures clean, controlled load switching; a worn or failed unit can cause arcing, output instability, or failure to energize the load circuit.
• Electrical Safety Critical Component — In high-amperage generator systems, a correctly rated contactor is essential for preventing overheating, contact welding, and electrical fault conditions.

A contactor is an electrically controlled switch used to connect and disconnect high-current circuits under load. In a generator, the contactor manages the flow of output power to the load — opening and closing the circuit in response to control signals from the generator's management system. When a contactor fails, symptoms can include the generator running but failing to deliver power to the connected load, intermittent output, or visible arcing and heat damage at the contact points. Replacing a faulty contactor with the correct OEM-rated unit restores reliable, safe power delivery and protects downstream electrical equipment.
