Robertshaw 5300-618 Thermostat

The Robertshaw 5300-618 is a heavy-duty single pole single throw (SPST) electric cooking control designed for demanding commercial applications. This snap-acting thermostat features a direct-acting mechanism with silver contacts to ensure sustained accuracy and high-cycle reliability in high-temperature environments. Testing at a range of 100°F to 450°F, this Open-High (NCO) switch is engineered to break the circuit upon temperature rise, making it a critical safety and regulation component for industrial ovens, fryers, and professional kitchen equipment.

Built for durability, the Robertshaw 5300-618 thermostat includes a 60-inch nickel-plated capillary and an 11-5/8" bulb, providing superior resistance to corrosion and rapid thermal response. This Uni-Kit model arrives with a 4-way slip-fit dial and mounting hardware, facilitating a seamless field replacement for a wide array of OEM parts from brands like Gemline, General Electric, and Ranco. With an electrical rating supporting 30 Amps at 277V AC, this commercial electric thermostat provides the rugged performance required by veteren technicians for precise thermal management and system protection.

• Broad Operating Range: Covers 100°F to 450°F for versatile use across fryers and ovens.
• Nickel Construction: 60" nickel-plated capillary and bulb provide enhanced protection against oxidation and chemical wear.
• Snap-Action Reliability: High-integrity SPST switch mechanism prevents arcing and maintains setpoint precision.
• Interchangeable Design: Replaces cross-references including SP-188, 54B700950P1, and 20120 for simplified inventory.
• High Electrical Capacity: Rated for up to 30A at 277V, suitable for heavy-duty heating elements.

What is the switch action for the 5300-618?
This model utilizes an "Open-High" (NCO) configuration, meaning the contacts open to cut power to the heating circuit once the setpoint temperature is reached.

Is this compatible with 120V and 277V systems?
Yes, the 5300-618 is rated for use in both 120V AC and 277V AC applications, making it a standard choice for a variety of commercial electrical feeds.

What is the difference between this and a standard copper capillary?
The nickel plating on the 60" capillary tube offers increased resistance to the corrosive fats and high-heat conditions typical in commercial fryers and industrial cooking equipment compared to standard copper.
