Robertshaw 5500-213M Switch

The Robertshaw 5500-213M Infinite Switch is a heavy-duty, voltage-sensing replacement control engineered for precision management of resistive loads in industrial and commercial heating equipment. As a direct M Series 240V infinite switch upgrade, this unit replaces the discontinued VSI (INF) models and the Robertshaw 5500-213. It features a 22.5% low-end input capability, making it ideal for applications requiring consistent, proportionate heat control such as electric ranges, warming drawers, and commercial space heaters. The 5500-213M rotary switch is rated for up to 15 Amps at 240V AC and is designed to withstand ambient temperatures up to 257°F. Its universal square break-off shaft allows technicians to field-adjust the stem length to match existing OEM dials, ensuring a clean installation on various panel depths. This INF-240-597B cross-reference part is housed in a compact body to fit tight control boxes and includes multiple mounting options, including screw or bushing mounts, to streamline standard maintenance and repairs.

• Universal Compatibility: Includes specialized shaft adaptors and a break-off stem to accommodate most electric range and heater dial configurations.
• Technical Specifications: 240V AC operation, 15 Amps maximum load, and 22.5% initial heat input for precise thermal regulation.
• Durable Construction: Built as a parallel circuit, voltage-sensing control that meets strict agency specifications for reliability in high-temperature environments.
• Flexible Mounting: Designed for easy integration with existing screw-mount or bracket-mount systems found in commercial kitchens and industrial units.

• Will this work with my original equipment knobs? Yes, the 5500-213M is a Uni-Kit model that includes a sprue tree of adaptors allowing it to interface with most original equipment dials once the shaft is trimmed to the correct depth.
• Is this switch a push-to-turn or non-push-to-turn model? This depends on the specific assembly, but it is typically configured for standard rotary operation; always verify the mechanical detent action matches your application needs before final installation.
• Can I replace a 3-heat or 5-heat rotary switch with this? Yes, these infinite switches are designed to provide a universal replacement for multi-heat rotary switches by offering a continuous range of output power rather than fixed heat settings.
