The Lincoln Electric M20585-1 (9SM20585-1) is a 40 Amp, 2-pole thermal-magnetic circuit breaker designed to protect the auxiliary AC generator power output on engine-driven welder-generators. It serves as a primary line of defense for generator windings and connected tools against overcurrent conditions, specifically for 120V/240V outlets on compatible welding systems.
Features
Integrated environmental cover seal
Reinforced construction for high-vibration environments
Split-phase system isolation (breaks both hot legs)
Resistance to dust and temperature fluctuations
Calibrated for specific load capacity of auxiliary outputs
Standard mounting and connection points for control panel integration
