The Multiquip 0601820836 Over Current Relay DLW330X2 is a genuine OEM component designed for DLW400ESA4 and DLW330X2 series diesel light welders. Sourced directly from Multiquip, this relay meets the original electrical specifications required by these machines, ensuring proper circuit protection without adaptation or guesswork. Verified fitment on DLW330X2 and DLW400ESA4 models makes 0601820836 a straightforward service replacement when the original relay fails or trips beyond recovery.
Key Features
- Genuine OEM Electrical Spec — Matched to the correct trip threshold and contact rating for DLW-series welder protection circuits, not a generic substitute.
- Direct Drop-In Replacement — Engineered to the same mounting footprint and terminal configuration as the original relay for a clean installation.
- Confirmed Fitment — Compatible with DLW330X2 and DLW400ESA4 Multiquip diesel light welder models.
- Circuit Protection Where It Counts — A correctly functioning over current relay prevents sustained overloads from damaging the welder's generator head and wiring harness; a failed relay leaves those components exposed.
- Electrical Safety Compliance — Replacing a faulty over current relay with the correct OEM part restores the intended fault-interruption capability, an important safety function in any generator-welder application.
An over current relay monitors the electrical output of the welder-generator and interrupts the circuit when current draw exceeds a safe operating threshold. This protects the machine's alternator windings, wiring, and connected loads from heat damage caused by prolonged overload conditions. When the relay fails or loses its calibrated trip point, the welder loses that layer of automatic protection, putting both the equipment and the operator at risk.
