Danfoss 017-500366 Temperature Control

The Danfoss 017-500366, also known as the RT101 Temperature Control, is a heavy-duty single-pole double-throw (SPDT) thermostat engineered for industrial and marine cooling applications. Built with a vapor charge sensing element, this RT series thermostat provides reliable regulation within a temperature range of 25°F to 120°F (-4°C to +50°C). The adjustable differential allows for precise cycling, making it ideal for HVAC refrigeration controls and boiler room monitoring where high-vibration resistance is required. Use this Danfoss temperature switch for air-side control or liquid temperature management in mechanical rooms. The enclosure is rated for IP66, ensuring internal components stay protected against dust and heavy spray. For contractors seeking a rugged commercial thermostat replacement, the 017-500366 offers a field-proven mechanical temperature controller solution that maintains calibration under demanding operational loads without the drift common in lower-tier alternatives.

Technical Features:

• SPDT contact system allows for both heating and cooling applications or alarm signaling.
• Wide ambient temperature range support for engine rooms and outdoor enclosures.
• High-durability IP66 rated housing prevents ingress in humid or wash-down environments.
• Adjustable differential range of 2.7°F to 12.6°F (1.5K to 7K) for tailored system cycles.
• Remote bulb sensing element for accurate thermal feedback away from the control body.

Common Technical Questions:

Is the Danfoss 017-500366 suitable for marine applications?
Yes, the RT series is designed with shock and vibration resistance, meeting the requirements for maritime shipboard use and heavy industrial machinery.

What is the maximum contact load for the RT101?
The SPDT switch typically handles an AC-1 (inductive) load of up to 10A at 400V, though checking the specific motor start-up amperage against the contact rating is recommended.

Can I use this control for both heating and cooling?
The SPDT configuration allows you to wire to the 'make' or 'break' terminals, facilitating its use as a high-limit cut-out or a standard cycling thermostat.
