0193586104 - ESAB 20 Amp Replacement Circuit Breaker

Reliable Circuit Protection for Industrial Welding Equipment

The ESAB 20A Circuit Breaker (Part Number 0193586104) is a critical component designed to safeguard the electrical integrity of high-performance welding machines. In the demanding environment of industrial fabrication, power fluctuations and internal faults can pose significant risks to sensitive electronic components. This circuit breaker serves as the primary line of defense, automatically interrupting current flow when it exceeds the safe 20-amp threshold, thereby preventing catastrophic damage to the power source, rectifiers, and control boards.

Engineered to meet ESAB's rigorous specifications, this breaker utilizes a robust thermal-magnetic tripping mechanism. The thermal element provides protection against low-level overloads that persist over time, while the magnetic element responds instantaneously to high-current short circuits. This dual-action protection ensures that the welding machine is protected against a wide range of electrical anomalies without nuisance tripping during normal operation. The unit features a durable toggle switch that provides a clear visual indication of the circuit status—ON or TRIPPED—allowing maintenance personnel to quickly diagnose power issues.

Using genuine OEM replacement parts like the ESAB 0193586104 is essential for maintaining the safety certification and operational reliability of your equipment. Generic breakers may not possess the specific trip curves required for the inductive loads typical of welding transformers and inverters. This component is designed for seamless integration into the control panel of compatible ESAB power sources, ensuring a secure fit and reliable electrical connection. Whether performing routine maintenance or emergency repairs, this 20A breaker restores the safety functionality of your machine, minimizing downtime and extending the service life of your capital equipment.

Installation should always be performed by qualified personnel familiar with industrial electrical systems. By choosing this authentic ESAB component, you ensure that the replacement matches the original design parameters of the welder, maintaining the manufacturer's intended safety margins and performance standards.
