259975 - Miller Filtair 30HP 575V Motor Overload Relay

Protect Your Industrial Fume Extraction Investment

The Miller 259975 Overload Relay is a critical component designed specifically for heavy-duty Miller Filtair fume extraction systems operating on 575V industrial power grids. In the demanding environment of industrial welding, maintaining air quality is paramount for worker safety and regulatory compliance. The Filtair system relies on powerful motors to cycle air and remove hazardous particulates. This overload relay serves as the primary line of defense for the system's 30 HP motor, ensuring that electrical anomalies do not result in catastrophic equipment failure.

Genuine Miller OEM Quality

When dealing with high-voltage equipment, precision and compatibility are non-negotiable. This is a genuine Miller Electric OEM part, engineered to the exact specifications of your Filtair unit. Using aftermarket or generic relays in a 575V system can lead to improper trip curves, nuisance tripping, or, worse, a failure to trip during an actual overload event. The Miller 259975 is calibrated to handle the specific inrush currents and running loads of Miller's high-performance extraction motors, providing peace of mind and operational stability.

Designed for 575V Industrial Applications

This specific relay is rated for 575 Volts, a standard voltage for heavy industrial machinery in many regions, particularly in Canada. It is distinct from standard 230V or 460V components. Installing the correct voltage-rated relay is essential for the longevity of the machine. The 30 HP rating indicates this part is intended for large-scale, central, or high-capacity extraction units that service multiple welding stations or heavy fabrication areas. By monitoring the current flowing to the motor, this device detects thermal buildup caused by mechanical jams, phase loss, or excessive duty cycles, cutting power before the motor windings can melt or degrade.

Maintenance and Reliability

Routine maintenance of your fume extraction infrastructure involves checking electrical protection devices. If your system is experiencing frequent trips or if the existing relay has failed due to age or a significant electrical fault, replacing it with the Miller 259975 is the only way to restore full protection. Keep your shop air clean and your machinery running efficiently with this essential repair component.
