Bomag 421013019 Relay

The Bomag 421013019 Relay is a genuine OEM electrical relay designed for Bomag BM-series cold milling machines and BF 600-series pavers. This relay delivers an exact match to the original component, ensuring correct circuit switching behavior across the full range of compatible equipment. It fits models including the BM1300/30, BM1200/30, BM2000/60, BM2000/50, BM1000/30-2, BM1300/30-2, BM1300/30-T3, BM1200/30-T3, BF 600 C-E, BF 600 P-E, BF 600P HSE, BF 600 P HCE, BF 600C HCE, and BF 600C HSE. Sourced directly from Bomag, this relay meets the same electrical specifications as the part it replaces, making it a straightforward swap for experienced technicians and service teams.

Key Features

• Genuine OEM Electrical Spec — matched to Bomag's original coil resistance, switching capacity, and contact rating for this relay position, so the circuit performs exactly as engineered
• Direct Plug-In Replacement — identical connector footprint and terminal configuration to the factory relay, dropping into the existing socket without rework
• Broad Milling and Paving Coverage — fits BM-series cold milling machines including BM1000/30-2, BM1200/30, BM1200/30-T3, BM1300/30, BM1300/30-2, BM1300/30-T3, BM2000/50, and BM2000/60, plus BF 600-series pavers including BF 600 C-E, BF 600 P-E, BF 600P HSE, BF 600 P HCE, BF 600C HCE, and BF 600C HSE
• Protects Downstream Electrical Systems — a correctly rated relay routes and isolates current as designed, preventing overload damage to control modules, solenoids, and wiring harnesses that a failed or mismatched relay can cause
• Verified by Part Number 421013019 — cross-check your machine's service manual or parts diagram against part number 421013019 before ordering to confirm fitment for your specific serial range

A relay is an electrically operated switch that allows a low-current control signal — from a machine's control panel or ECU — to open or close a higher-current circuit powering components such as fuel solenoids, hydraulic valves, cooling fans, or warning systems. On cold milling machines and pavers, relays are embedded throughout the electrical architecture, and a failed relay can cause a specific function to stop responding entirely or behave erratically, often mimicking faults in more expensive downstream components. Replacing a faulty relay with a correctly rated OEM unit restores normal switching function and protects the broader electrical system from the voltage spikes and heat a degraded relay can generate.
