952173 - ESAB 3-Pole Welding Contactor 60A 600V

Reliable Power Control for Industrial Welders

The ESAB 952173 Contactor is a critical electromechanical component designed for heavy-duty welding power sources. Engineered to manage high-voltage and high-amperage circuits, this 3-pole contactor is rated for 60 Amps and up to 600 VAC. It serves as the primary switching mechanism in compatible ESAB welding machines, controlling the flow of power to the transformer or inverter bridge.

In industrial environments, contactors are subjected to frequent cycling and high electrical loads. Over time, the internal contacts can become pitted, welded, or burnt, leading to machine failure, erratic arc performance, or the inability to turn the output off. Replacing a failing unit with this genuine OEM part ensures your equipment returns to factory specifications, maintaining safety and operational efficiency.

Key Technical Specifications

This unit features a robust 3-pole design, making it suitable for three-phase power input management. Its 600V insulation rating ensures it can safely handle standard industrial voltages (480V, 575V/600V) without risk of flashover. The 60A current rating provides ample overhead for the power demands of medium-to-heavy industrial welding systems.

Installation and Maintenance

As an internal electrical component, this contactor should be installed by a qualified technician. Proper installation ensures that the coil voltage matches the control circuit and that all power connections are torqued to specification to prevent overheating. Using genuine ESAB parts like the 952173 guarantees physical fitment and electrical compatibility with your specific machine model.
