Multiquip LBD1132 Contactor, 3 Pole, 75A, 12VDC

The Multiquip LBD1132 is a genuine OEM Contactor, 3 Pole, 75A, 12VDC designed for DCA150SSJU4F3 and DCA180SSJU4F series Super-Silent diesel generators. As a direct OEM replacement sourced from Multiquip, this contactor meets the original electrical specifications required to keep your generator operating safely and reliably under load. Verified fitment covers DCA150SSJU4F3, DCA180SSJU4F3, and DCA180SSJU4F models, including 60Hz variants, so you can order with confidence knowing LBD1132 is the correct part for your unit.

Key Features

• OEM-Rated Switching Capacity — Rated at 75 amps across 3 poles with a 12VDC coil, matching the exact electrical load-switching specification of the original contactor in these generator models.
• Direct-Mount Replacement — Engineered to install in the same position and wiring configuration as the factory unit, with matching terminal layout for a clean, secure connection.
• Confirmed Fitment for Super-Silent Series — Compatible with DCA150SSJU4F3, DCA180SSJU4F3, and DCA180SSJU4F generators, including 60Hz variants of each model.
• Protects Generator Output Circuits — A correctly functioning contactor manages high-current switching between the generator and connected load circuits; a failed unit can cause output loss, erratic power delivery, or failure to transfer load.
• Genuine Multiquip OEM Part — Supplied as a genuine OEM component under part number LBD1132, ensuring the correct coil voltage, contact rating, and terminal configuration are preserved.

A contactor is an electrically controlled switch designed to handle high-current circuits — in a generator, it manages the switching of power between the generator output and the connected electrical load. The 3-pole configuration means it simultaneously switches all three phases of AC power, which is critical for balanced load distribution in commercial generator applications. When a contactor wears out or fails, symptoms can include the generator running but delivering no output power, intermittent load dropout, or failure to engage under automatic transfer sequences — all of which make prompt replacement essential for uninterrupted operation.
