0558008254 - ESAB 5A DPST Circuit Breaker Switch 250VAC/65VDC

Reliable Circuit Protection for ESAB Equipment

The ESAB 0558008254 is a high-quality Circuit Breaker Switch designed specifically for ESAB welding power sources and plasma cutting systems. As a critical component in the electrical management of industrial machinery, this device serves a dual purpose: it functions as a manual on/off control while simultaneously providing automatic overcurrent protection. This specific unit is rated for 5 Amperes, making it suitable for protecting control circuits or auxiliary power lines within the machine that require precise current limitation to prevent damage to sensitive electronic components.

Technically, this component features a Double Pole Single Throw (DPST) configuration. This design allows the switch to control two separate circuit lines simultaneously, opening or closing both contacts with a single actuation. This is particularly important in industrial equipment where isolating both the live and neutral lines (or positive and negative in DC applications) is required for safety and complete circuit isolation. The breaker is rated for operation at up to 250 Volts AC and 65 Volts DC, providing versatility across different power input configurations found in ESAB's global equipment lineup.

Using genuine OEM parts like the 0558008254 ensures that the replacement component meets the exact thermal and magnetic trip curves originally specified by ESAB engineers. Generic breakers may fit physically but often lack the precise trip characteristics required to protect specific welding inverter boards or cooling fans. This switch is built to withstand the vibration, thermal cycling, and dust exposure common in welding environments, ensuring a long service life and reducing the frequency of maintenance downtime. Installation is straightforward with its standard panel-mount design, allowing maintenance personnel to quickly swap out faulty units and restore equipment to full operational status.

When diagnosing equipment failures, a faulty circuit breaker is a common culprit for machines that refuse to power on or intermittently shut down. Replacing a worn or tripped breaker with this authentic ESAB part guarantees that the machine's safety mechanisms are restored to factory standards. Whether used in a PowerCut plasma cutter or a specific welding power source, this 5A DPST breaker is an essential spare part for maintaining the reliability and safety of your ESAB fleet.
