Multiquip 49718 Contactor 4 Pole 4NO 20A

The Multiquip 49718 Contactor 4 Pole 4NO 20A is a genuine OEM electrical contactor designed for MLT25DCA Towable Tower light towers. As a direct OEM replacement, this contactor is sourced from Multiquip to meet the exact electrical specifications of the original component. Fitment is confirmed for the MLT25DCA Towable Tower series, making 49718 the correct part to specify when servicing the control circuit on these units.

Key Features

• OEM-Rated Electrical Spec: — Rated at 20A with a 4-pole, 4 normally open configuration — matched to the original switching load requirements of the MLT25DCA Towable Tower.
• Direct OEM Replacement: — Mounts and connects in place of the original contactor with no circuit modifications; terminals and pole layout mirror the factory unit.
• Confirmed Fitment: — Verified for MLT25DCA Towable Tower light towers; cross-reference part number 49718 before ordering to confirm your unit.
• Stable Switching Performance: — A correctly rated contactor maintains clean, consistent power switching to tower circuits; an undersized or worn contactor can cause voltage drop, arc damage, and nuisance tripping under load.
• Electrical Safety Compliance: — Using the correct OEM-rated contactor in a lighting and power distribution circuit is critical to preventing overload faults, contact welding, and potential fire hazards in the electrical panel.

A contactor is an electrically controlled switch used to manage high-current circuits — in a light tower like the MLT25DCA, it handles the switching of power to the lighting load and other downstream circuits. The 4-pole, 4 normally open design means all four contacts open at rest and close simultaneously when the coil is energized, providing clean, reliable circuit closure under operating voltage. When a contactor fails — through contact wear, coil burnout, or arc erosion — lights may fail to illuminate, circuits may trip unexpectedly, or the tower may become unsafe to operate until the faulty component is replaced.
