Robertshaw 5300-027 Thermostat

The Robertshaw 5300-027 Thermostat is a heavy-duty, snap-acting electric temperature control engineered for high-demand industrial and commercial heating applications. As a 5300 Series mechanical thermostat, this SPST temperature switch features a broad 140°F to 500°F (60°C to 260°C) range, making it a critical component for electric cooking equipment, deep fryers, and industrial ovens. The unit utilizes a 48-inch capillary with a 1/4" x 7-5/8" nickel-plated sensing bulb to ensure precise thermal feedback and long-term durability in corrosive environments. Designed for 120V to 277V AC operation, this Robertshaw 5300-027 replacement handles resistive loads up to 25 Amps, providing the reliable cycling needed to maintain consistent system temperatures. This HVAC cooking control includes a 4-way mounting bracket and a breakaway stem for maximum field flexibility. Techs typically use this high-temperature thermostat for Duke Manufacturing and Johnstone Supply cross-references where mechanical reliability is non-negotiable.

• Broad Operating Range: Precision 140-500 degree thermostat control suitable for high-heat commercial kitchen and processing equipment.
• Enhanced Durability: Features nickel-plated capillary and bulb to resist oxidation and chemical wear in harsh environments.
• Field Versatility: Equipped with a 48” capillary and breakaway stem to adapt to various cabinet depths and mounting configurations.
• High Electrical Capacity: Rated for 25A resistive loads at 250V AC, supporting heavy-duty heating elements without external relay assistance.

• What are the compatible cross-references for this model? This unit is a direct replacement for Duke 12081, 12173, and 2081, as well as Johnstone F16-761 and Uni-Line 23706.
• Does this include the auxiliary switch? Yes, the 5300 series design often includes an auxiliary switch for additional circuit control, though it can replace non-auxiliary models by disregarding the extra terminals.
• What is the mechanical differential? The 5300-027 operates with a 12°F mechanical differential, ensuring responsive cycling to maintain tight temperature tolerances.
