OVERVIEW

Get Your Welder Back Online with the Right Breaker

There is nothing more frustrating than a welder that won't turn on or a breaker that keeps tripping right when you strike an arc. If your ESAB machine is down due to a faulty main switch or breaker, the ESAB 951181 Circuit Breaker is the direct replacement you need. This isn't just a generic hardware store part; it is the specific 3-pole, 30 Amp, 480 Volt breaker designed to match the power requirements of your industrial welder.

Circuit breakers in welding machines take a beating. They handle high voltage, constant on-off cycling, and the heat generated during long shifts. Over time, the internal contacts can wear out, or the mechanism can become weak, leading to nuisance tripping or a complete failure to reset. Swapping in this fresh OEM breaker restores reliable power control to your machine. Because it is a 3-pole unit, it handles all three legs of your 480V three-phase power simultaneously, ensuring that if one line has an issue, the whole machine shuts down safely to prevent single-phasing damage to your motors or transformers.

Don't risk your expensive power source with a "close enough" aftermarket part. This ESAB 951181 fits exactly where the old one came out, making the repair straightforward for your shop electrician. It’s built tough to handle the shop environment, meaning once you fix it, you can forget about it and get back to laying beads. Keep your production schedule on track and your equipment safe with the correct replacement parts.

Why Choose OEM?

  • Perfect Fit: No modifying mounts or struggling with connections.
  • Correct Rating: 30A at 480V is exactly what your machine specs call for.
  • Peace of Mind: Protects your investment from electrical spikes.

FAQ

This breaker fits specific ESAB industrial power sources that require a 3-pole, 30A, 480V breaker. Please check your machine's parts manual or the existing breaker's markings to confirm compatibility.

Yes, this is a 3-pole circuit breaker, which is designed for use with 3-phase electrical systems commonly used in industrial welding.

Installation involves working with high-voltage industrial power (480V). It should only be performed by a qualified electrician or certified equipment repair technician to ensure safety.

Symptoms include the breaker tripping immediately upon turning the machine on, the breaker refusing to reset (staying in the 'off' or 'trip' position), or the machine not receiving power on all phases.

While the voltage rating (480V) is a maximum, the amperage rating (30A) and trip curve must match your machine's requirements. Always replace with the exact specifications listed in your manual.

Yes, this is a genuine ESAB replacement part, ensuring it meets the original manufacturing specifications for quality and safety.

3-Pole means the switch disconnects or protects three separate electrical conductors simultaneously, which is standard for 3-phase power.

Typically, circuit breakers are sold as the unit itself. You usually reuse the existing mounting screws or rail clips from the machine, unless specified otherwise.
