Robertshaw 5500-134M Switch

The Robertshaw 5500-134M Switch is a professional-grade, voltage-sensing infinite switch engineered for precise power regulation in commercial resistive load applications. As the direct OEM replacement for 5500-134 and the obsolete INF series, this 120V electric infinite switch features a compact M-series design that fits within tight control panels without compromising performance. It supports a 15 Amp electrical rating and is built for a 100W to 3600W range, ensuring consistent cycling for electric ranges, hot plates, and warming drawers. This Uni-Kit infinite switch includes a 2-1/8 inch break-off shaft with a universal D-stem profile, allowing contractors to field-modify the length to match existing dial depths. The 5500-134M 120V control utilizes a heavy-duty rotary design with 8-32 UNC mounting threads for superior screw engagement compared to stamped alternatives. Reliable and UL-certified, it provides low-to-high detent control with a 5% input at the low setting for accurate temperature management.

• Direct Replacement: Seamlessly replaces Robertshaw 5500-134, INF-120-1152, and INF-120-598 models.
• Field Adaptable: Features a 2-1/8" grooved break-off shaft and universal mounting hardware to accommodate various appliance depths.
• Rugged Construction: Rated for high-ambient environments up to 180°F (82.2°C) with a durable double-line break mechanism.
• Versatile Application: Ideal for commercial kitchens, including barbecue grills, space heaters, and quartz heating elements.
• Enhanced Mounting: Uses a 8-32 UNC nut for more secure 2.5-thread engagement versus standard thin-metal helix designs.

Is the 5500-134M compatible with 240V systems?
No, this specific model is rated for 120V AC applications. For 240V requirements, technicians should utilize the 5500-200 series Uni-Kits.

Does this kit include a new dial?
The 5500-134M is a Uni-Kit designed to reuse the original equipment dial; however, it includes shaft adapters to ensure a proper fit with the existing knob.

What is the maximum amperage supported?
The switch is rated for 15 Amps at 100°C (210°F) or 13 Amps at 125°C (257°F) for resistive loads.
