The Multiquip ZPPC190325 Amp Mini Relay C30HDG 50/20 is a genuine OEM relay designed for the Mayco C30HDG concrete pump. Sourced directly from Multiquip, this relay meets the exact electrical specifications required for correct operation of the C30HDG control circuit. Choosing the correct OEM relay ensures the switching function performs as intended, protecting downstream components and keeping the pump's electrical system operating within spec.
Key Features
- OEM-Specified Switching Capacity — Rated to the 50/20 amp specification required by the C30HDG electrical circuit, delivering the correct load-handling capacity for this application.
- Exact-Match Replacement — Drop-in fit for the Mayco C30HDG relay socket; installs directly without modification to wiring or mounting hardware.
- Confirmed C30HDG Fitment — Verified for use on the Mayco C30HDG cycloidal concrete pump platform.
- Protects Electrical System Integrity — A correctly rated relay prevents overload conditions that can damage control boards, solenoids, and other electrical components in the pump circuit.
- Genuine Multiquip OEM Quality — Manufactured to Multiquip's sourcing standards, ensuring coil resistance, contact material, and terminal configuration match the original component exactly.
A relay is an electrically operated switch that allows a low-current control signal to open or close a higher-current circuit safely. In a concrete pump like the C30HDG, relays are critical to controlling solenoids, motors, and other high-draw components from the machine's control panel. When a relay fails — due to worn contacts, coil burnout, or incorrect amperage rating — the circuit it controls either stops functioning entirely or behaves erratically, which can halt pumping operations or cause unintended component activation. Replacing a failed relay with the correct OEM-rated part restores predictable, safe switching behavior.
