OVERVIEW

Industrial Grade Circuit Protection

The ESAB 951180 Circuit Breaker is a critical component designed to safeguard high-performance welding power sources and industrial machinery. Engineered with a 2-pole configuration and a 50-amp rating, this breaker serves as a primary line of defense against electrical overloads and short circuits. In the demanding environment of industrial fabrication and MRO (Maintenance, Repair, and Operations), maintaining the electrical integrity of your equipment is paramount. This component ensures that current flow remains within safe operational limits, tripping automatically when limits are exceeded to prevent catastrophic damage to internal electronics and transformers.

As a genuine replacement part, this circuit breaker is manufactured to meet the rigorous specifications required by ESAB welding machines. Using non-OEM electrical components in sophisticated power sources can lead to nuisance tripping, improper voltage regulation, or failure to trip during a fault, posing significant safety risks. The 951180 offers precise calibration for the specific inrush currents and duty cycles associated with welding operations, ensuring that your machine remains powered during standard operation while reacting swiftly to genuine faults.

Installation of this 2-pole breaker should be performed by qualified personnel familiar with industrial electrical systems. Its robust casing is designed to resist the vibration and thermal fluctuations often present in workshop environments. Whether you are troubleshooting a power-up failure or performing preventative maintenance on an aging fleet of welders, replacing a worn or faulty breaker with this exact-spec unit restores the reliability and safety compliance of your equipment.

Key Technical Considerations:

  • Amperage Rating: Strictly rated for 50A to match machine input/output requirements.
  • Configuration: 2-Pole design breaks both live conductors simultaneously for complete isolation.
  • Compatibility: Verified for specific ESAB power source models requiring part number 951180.

FAQ

This circuit breaker is rated for 50 Amps.

This is a 2-Pole circuit breaker.

Yes, this is a genuine ESAB replacement part, SKU 951180.

It is compatible with specific ESAB welding machines and plasma cutters. Please check your machine's parts manual for part number 951180 to confirm fitment.

No, this breaker is designed as a component for industrial machinery and may not fit or meet the code requirements for residential load centers.

Symptoms include the machine failing to power on, the breaker tripping immediately upon reset, the switch feeling loose or not clicking into place, or physical signs of heat damage.

Typically, the breaker is supplied as the unit itself. You generally reuse the existing mounting clips or hardware inside the machine chassis.

Due to the high voltage and current involved in welding equipment, installation should be performed by a qualified electrician or equipment repair technician.
