0194384003 - ESAB Thermal Overload Switch 0194384003

Genuine ESAB 0194384003 Thermal Protector UL

The ESAB 0194384003 Thermal Protector UL is a critical replacement component designed to maintain the operational integrity and safety of your ESAB welding equipment. As a genuine Original Equipment Manufacturer (OEM) part, this thermal protector is engineered to the exact specifications required by ESAB power sources, ensuring a seamless fit and reliable performance. In the industrial MRO sector, using authentic parts is paramount to minimizing downtime and avoiding the risks associated with generic aftermarket components that may not trigger at the correct temperature thresholds.

This specific unit is UL-listed, indicating it has undergone rigorous testing by Underwriters Laboratories to meet strict safety standards. For procurement managers and maintenance teams, stocking critical spares like the 0194384003 ensures that production halts caused by minor component failures are resolved immediately. Thermal protectors are essential safety devices that monitor the internal temperature of the welding machine's transformer or inverter components. When these components exceed their safe operating temperature—often due to exceeding the duty cycle or blocked airflow—the thermal protector interrupts the circuit to prevent catastrophic failure.

Replacing a faulty thermal switch with this genuine ESAB part restores the machine's ability to self-regulate, protecting the significant investment made in the welding power source. It is compatible with specific ESAB models; please verify the part number against your equipment's service manual or parts diagram. By choosing the ESAB 0194384003, you are opting for a component that guarantees the longevity of your fleet and adherence to factory safety protocols.

Key Benefits for Inventory & Maintenance:
