Multiquip P0273-4 Terminal Insulator

The Multiquip P0273-4 Terminal Insulator is a genuine OEM component designed for the DCA Super-Silent and Ultra-Silent generator series, including the DCA70SSIU4F, DCA150SSJU4F3, DCA180SSJU4F3, DCA400SSI4F, DCA400SSI4F3, DCA600SSV4F3, and related 4F-tier variants. Sourced directly from Multiquip, this part meets the exact material and dimensional specifications of the original component it replaces. It is a direct fit for the electrical terminal assemblies found across the DCA generator lineup, requiring no reworking of existing connections. If you are servicing a DCA-series generator and need confidence in fitment, the P0273-4 is the correct OEM choice.

Key Features

• Genuine OEM Dielectric Integrity — Manufactured to the same insulation grade and material composition as the original, ensuring proper electrical isolation at the terminal connection point.
• Direct Terminal Fit — Designed to seat correctly on the existing terminal hardware in DCA-series generators without trimming, shimming, or adapter hardware.
• Broad DCA Series Compatibility — Fits DCA70SSIU4F, DCA150SSJU4F3, DCA180SSJU4F, DCA400SSI4F, DCA400SSI4F3, DCA600SSV4F3, and multiple 60 Hz variants across the Super-Silent and Diesel Powered Generator families.
• Electrical Safety at the Terminal — A compromised or missing terminal insulator creates a risk of short circuit, arcing, or unintended contact at a live connection point; replacing it restores proper isolation and safe generator operation.
• Verified Multiquip Part Number — Ordered and fulfilled as P0273-4, so you can cross-reference against your service manual or parts diagram with confidence before placing your order.

A terminal insulator is a non-conductive sleeve, collar, or cap fitted over or around an electrical terminal to prevent unintended contact between live conductors and surrounding metalwork or adjacent wiring. In a generator, terminals carry significant current, and the insulators that protect them are critical to both safe operation and long-term electrical reliability. When a terminal insulator cracks, deforms, or goes missing, it exposes the connection to potential short circuits, arcing, or ground faults — any of which can interrupt power output or cause broader electrical damage to the unit.
