0193922001 - ESAB B16-30-01 Replacement Contactor Relay

Technical Overview of the ESAB B16-30-01 Contactor

The ESAB Contactor B16-30-01 (SKU: 0193922001) is a critical electromechanical component designed for the power management systems of industrial welding machines. As a B-series contactor, it is engineered to handle the rigorous demands of high-amperage switching associated with welding power sources. This unit features a 3-pole configuration for the main power circuit, which is standard for three-phase equipment or heavy-duty single-phase splitting, ensuring balanced power distribution to the transformer or inverter block.

One of the defining technical characteristics of the B16-30-01 model is its auxiliary contact configuration. It includes one Normally Closed (NC) auxiliary contact ('01' designation). This is essential for control logic, often used for safety interlocks, status indication, or ensuring that specific circuits are de-energized when the main power is active. The contactor utilizes high-grade conductive materials for its contact tips to minimize electrical resistance and heat generation, which is vital for maintaining the duty cycle of the welding machine.

Installation of this component restores the original functionality of ESAB equipment that utilizes the B16 frame size. It is designed to mount securely within the machine's electrical cabinet, with terminal connections that ensure tight, vibration-resistant coupling with the machine's wiring harness. For maintenance professionals and industrial electricians, using the specified B16-30-01 ensures compliance with the machine's original electrical schematics and safety ratings.
