Robertshaw 5500-234 Infinite Switch

The Robertshaw 5500-234 Infinite Switch is a professional-grade, voltage-sensing control engineered for precise 240V AC resistive load management in commercial cooking and HVAC equipment. Designed as a primary replacement for Robertshaw INF and VSI series energy regulators, this M-Series unit features a compact, low-profile housing that allows for streamlined installation in tight control panels. Operating with a 5% input at low, it facilitates granular heat regulation for surface elements, warming drawers, and industrial ovens. This rotary energy regulator provides a 15-Amp resistive load capacity at 200°F and maintains a 13-Amp rating up to a maximum ambient temperature of 257°F. The 5500-234 infinite control includes a black dial for immediate visual reference and utilizes a "D" style stem for secure knob fitment. Technicians can rely on the double line break safety feature (on most models) and the robust 8-32 UNC nut mounting system to ensure a stable, high-performance interface in demanding environments.

• Universal Compatibility: Serves as a direct replacement for various OEM controls including Electrolux, Teledyne Still/Laars, and several Uni-Line series.
• Precision Thermal Management: Features a calibrated 5% minimum input to prevent temperature overshoot on low-heat cycles.
• High-Temperature Durability: Rated for ambient operation up to 257°F (125°C), making it ideal for high-density commercial galleys and heat zones.
• Versatile Mounting: Supports both screw and bushing mounting configurations with a 2-inch "D" stem that can be modified to match specific panel depths.
• Simplified Wiring: Standardized terminal layout allows for straightforward integration into existing parallel circuit 240V systems.

What is the maximum amperage rating for the Robertshaw 5500-234?
This switch is rated for a maximum resistive load of 15 Amps at 240V AC for ambient temperatures up to 200°F (93°C). For higher ambient environments up to 257°F (125°C), the rating is 13 Amps.

Can this switch replace an older VSI or INF model?
Yes, the 5500 M-Series is specifically engineered to replace the obsolete VSI (INF) series, offering identical electrical performance in a more compact physical footprint.

How do I handle the pilot light terminal if my unit doesn't use one?
If your application does not require a pilot indicator, the "P" terminal may remain unused. Always confirm your specific wiring diagram to ensure proper phase alignment on L1 and L2.
