Robertshaw 5500-287 Infinite Switch

The Robertshaw 5500-287 Infinite Switch is a high-performance 240V surface unit control engineered for precision temperature management in residential and commercial heating equipment. As a voltage-sensing, parallel circuit regulator, this 240V infinite switch provides a controllable range of output power from 100W to 3600W, allowing for fine-tuned thermal regulation of resistive loads. This specific model features a no-dial design and is frequently utilized as a direct OEM replacement part for Whirlpool and other major appliance brands. Designed with a compact footprint, the 5500-287 utilizes an 8-32 UNC nut mounting system for secure installation within tight control panels. The internal mechanism is rated for up to 15 Amps at 200°F (93°C) or 13 Amps at 257°F (125°C), ensuring operational stability in high-ambient environments found in commercial ranges, hot plates, and warming drawers. This rotary burner switch offers a robust double-line break and is compatible with numerous cross-references, making it a staple for contractors maintaining legacy and modern stovetop systems.

Key Benefits:

• Universal 240V Compatibility: Handles resistive loads from 100 to 3600 Watts, making it suitable for a wide range of heating elements.
• Industrial-Grade Build: Constructed to withstand high temperatures up to 257°F (125°C) without performance degradation.
• Compact M-Series Housing: Small physical dimensions allow for easy integration and replacement in space-constrained appliance housings.
• Secure Mounting: Features integrated 8-32 UNC threads for superior screw engagement and vibration resistance compared to stamped holes.

Common Questions:

Can the 5500-287 replace a 120V switch? No, this is a dedicated 240V AC component. Installing it in a 120V circuit will cause improper calibration and potential damage to the heating element.

How do I handle the wiring for L1 and L2? When replacing Hart or Proctor switches, verify lead orientation. Robertshaw infinites may have reversed L1 and L2 positions compared to some competitive models; always check your schematic for proper line-break polarity.

Is a dial included with this unit? No, this part number is the switch body only. It is designed to be used with existing dials or 1/4" D-stem compatible knobs.
