OVERVIEW

Reliable Power Switching with the ESAB 952251 Contactor Kit

Maintain the integrity and performance of your industrial welding equipment with the ESAB 952251 Kit Contactor 3P 150A 115VAC. In the demanding world of heavy fabrication and manufacturing, your welding power source is the heart of your operation. The contactor serves as the primary switch that engages the welding output, handling high currents repeatedly throughout the workday. When this component begins to fail, it can lead to erratic arc starts, power loss, or even complete machine failure. This genuine ESAB replacement kit is engineered to meet the exact specifications of your original equipment, ensuring a seamless repair and return to productivity.

The 952251 kit features a robust 3-pole design rated for a substantial 150 Amps. This high amperage rating makes it suitable for heavy-duty power sources that require reliable switching of three-phase input power or high-output welding circuits. The coil is designed to operate on 115 VAC, a standard control voltage found in many industrial welding machines. By using genuine OEM parts, you guarantee that the coil resistance, pull-in voltage, and drop-out voltage match your machine's control board logic perfectly, preventing potential damage to sensitive electronic components.

Installing the correct contactor is not just about functionality; it is also a matter of safety. Worn contactors can stick closed, leaving the electrode "hot" even when the trigger is released, or they can overheat due to pitted contacts. The ESAB 952251 is built with high-quality materials to resist pitting and welding of contacts, providing a long service life even under the stress of frequent cycling. Whether you are performing routine maintenance or an emergency repair, trust in the quality of ESAB to keep your shop running smoothly.

Key Benefits:

  • Genuine OEM Quality: Designed specifically for ESAB equipment compatibility.
  • High Capacity: 150A rating handles heavy industrial loads with ease.
  • Durable Construction: Engineered to withstand the harsh environment of welding shops.
  • Safety: Reliable switching prevents dangerous "hot electrode" situations.

FAQ

The coil voltage for this contactor is 115 VAC. Please verify your machine's control circuit voltage matches this before installation.

This is a 3-Pole (3P) contactor, meaning it has three sets of main power contacts that switch simultaneously.

The contactor is rated for 150 Amps, making it suitable for heavy-duty industrial applications.

Yes, this is a genuine ESAB OEM replacement part, ensuring perfect fit and compatibility with your ESAB equipment.

Common signs include a loud buzzing noise, the machine staying 'hot' when the trigger is released, or the welder failing to output power despite the fan running.

No, this contactor requires 115 VAC to activate. Using it on a 24V circuit will not provide enough power to close the contacts.

Most ESAB repair kits include a basic instruction sheet, but we recommend consulting your specific machine's service manual for the correct replacement procedure.

No, it fits specific models that require a 150A, 3-pole, 115V coil contactor. Check your machine's parts list or the existing contactor's label to confirm compatibility.
