Multiquip 3011 5-Pin Micro Relay

The Multiquip 3011 is a genuine OEM 5-Pin Micro Relay designed for a wide range of Multiquip and Whiteman equipment, including MD105 and MD80 hydrostatic ride-on trowels, CA4HM, CA5BC, BS90C, BH11C, BH90C, JS60C, JH90C, JH55C, and HDA-Series walk-behind trowels, WRSPUDF and WRS5200 ride-on roller screeds, LT6K and LT6KV light towers, GAW180HE series arc welders, and GA2.5HR generators. As a genuine OEM component, the 3011 meets the exact electrical specifications set at the factory, ensuring it operates correctly within the control circuits of every listed machine. DHS Equipment supplies this part direct, so you can verify part number 3011 against your service documentation and order with confidence.

Key Features

• Genuine OEM Electrical Specification — Meets the precise switching capacity, coil resistance, and contact rating required for correct operation in Multiquip control circuits.
• Direct-Connect Replacement — 5-pin micro form factor matches the OEM relay socket exactly, allowing straightforward plug-in installation with no adapter or wiring modification.
• Broad Equipment Compatibility — Confirmed fitment across MD105, MD80, CA4HM, WRS5200, LT6K, GAW180HE, and numerous other Multiquip and Whiteman models — one part number covers the full range.
• Protects Control Circuit Integrity — A correctly functioning relay switches loads cleanly and prevents voltage spikes from reaching sensitive control boards; a failed relay can cause intermittent starting faults, non-responsive controls, or complete electrical shutdown.
• Electrical Safety Compliance — OEM-sourced relay ensures the switching component in safety-critical circuits — such as blade engagement or drive control interlocks — performs within the design envelope of the machine.

A 5-pin micro relay is an electromechanical switching device that uses a low-current signal from the machine's control circuit to open or close a higher-current load circuit. In equipment like ride-on trowels, roller screeds, and generators, relays are used throughout the electrical system to control functions such as engine starting, blade engagement, and auxiliary power switching. When a relay fails, the circuit it controls becomes unresponsive or unreliable — often presenting as an intermittent fault or a complete loss of function in one or more machine systems. Replacing a worn or failed relay with the correct OEM unit restores clean, predictable switching and protects downstream electrical components from the irregular current behavior a degraded relay can produce.
