Key Features

• Genuine OEM Electrical Specification — Built to the correct voltage and current ratings for the GX340K1 application, ensuring safe and consistent switching performance across supported equipment.
• Direct-Swap Installation — Matches the original mounting configuration and terminal layout, allowing a straightforward replacement without adapting wiring or hardware.
• Broad Multiquip Fitment — Compatible with MRH800GS, V305EH, GAW180HE, GAW180HE1, GAW180HEA, GA6HEB, GA6HZ, and R2000H models, covering walk-behind rollers, gasoline arc welders, and generators.
• Sustained Starting and Load Control — A properly functioning contactor assembly ensures reliable engagement of the starter and load circuits; a worn or failed unit can result in no-start conditions or erratic electrical behavior.
• Electrical Safety Integrity — Contactors handle high-current switching; using an OEM-rated assembly maintains correct arc suppression and insulation ratings critical to safe operation of welders and generators.

A contactor assembly is an electrically controlled switch used to manage high-current circuits — most commonly the starter motor circuit or primary power load circuit in engines and generators. When the operator triggers the start sequence, the contactor closes the circuit to allow current to flow to the starter or load. Over time, the contact points inside the assembly can pit, corrode, or fail to close fully, leading to slow cranking, intermittent starting, or a complete no-start condition. Replacing a worn contactor assembly restores proper circuit engagement and protects downstream electrical components from the irregular current draw caused by a degraded switch.
