Mr. Steam Contactor 24V-MS (50A/4Pole) delivers precise, high-capacity switching performance for advanced Mr. Steam residential and commercial systems. Featuring a four-pole configuration, it provides independent, synchronized control for multiple circuits, ensuring cleaner load separation, improved redundancy, and safer system isolation during maintenance. Rated for 50 amps, the contactor supports demanding steam generators and accessories without overheating, maintaining steady voltage and reliable performance under continuous duty. The 24-volt coil integrates seamlessly with standard low-voltage control logic, offering safe, responsive operation that prevents chatter and misfires. Constructed from corrosion-resistant, steam-rated materials, this robust unit withstands heat, humidity, and repeated cycling while protecting terminals and wiring. Its standardized footprint and clear labeling simplify installation and service, minimizing downtime and ensuring professional, code-compliant results. Dependable and efficient, it’s an essential component for maintaining peak electrical performance in your steam system.

  • Four-pole control – Independent, synchronized switching across four poles provides safer isolation for multi-circuit steam systems, enabling cleaner load separation, better redundancy, and reduced cross-talk for stable operation and clear maintenance lockout procedures.
  • 50A high-load capacity – Rated for 50 amps to handle demanding heaters and accessories without contact overheating. Generous headroom helps prevent nuisance trips, voltage sag, and premature wear, supporting consistent steam production during warm-up and peak usage.
  • 24V low-voltage coil – Works with common 24-volt control logic for safer service and broad compatibility. Reliable actuation reduces chatter and misfires, preserving precise sequencing of elements and safeguards for predictable starts, stops, and interlock behavior.
  • Durable, steam-rated build – Corrosion-resistant materials and robust contacts withstand heat, humidity, and frequent cycling in residential or commercial plant rooms. Long-life construction extends service intervals and protects wiring and terminals for dependable daily performance.
  • Quick, straightforward install – Standardized footprint and clearly labeled terminals simplify integration and upgrades, reducing wiring errors and downtime. Pro-friendly layout enables tidy routing and easy access for inspections, adjustments, and future replacements.
