Danfoss 060L115566 Temp Control

The Danfoss 060L115566 KP81 Temperature Control Thermostat is a rugged, industrial-grade solution designed for high-limit temperature regulation in steam, hot water, and process piping systems. This SPDT thermostat operates within a range of 80°C to 150°C (176°F to 302°F), making it a reliable choice for monitoring heat exchangers and boilers where strict thermal limits are required. Featuring a manual max reset function, the KP81 ensures your system remains offline for safety if temperatures exceed the set point, preventing equipment damage in critical applications. The remote bulb sensor (9.5 mm x 85 mm) is connected by a 2000 mm (78.7 in) capillary tube, allowing for flexible mounting of the IP30-rated enclosure away from the sensing point. With heavy-duty electrical ratings—including 16A AC1/AC3 and 10A AC15 at 400V—this control handles inductive and resistive loads without the need for additional contactors in many configurations. Its fixed differential of 9°C provides stable switching performance in high-demand industrial environments.

Key Benefits for Contractors

• Enhanced Safety: The manual reset mechanism acts as a high-temperature cutout to protect downstream components from thermal runaway.
• High Load Capacity: Robust SPDT contacts allow for direct control of single-phase motors and heating elements up to 16A.
• Versatile Installation: The 2-meter capillary provides sufficient lead for mounting the control on a panel while keeping the probe in the flow stream.
• Industrial Durability: NEMA 1/IP30 enclosure protects the internal mechanism from dust and debris common in mechanical rooms.
• Broad Compliance: Meets UL, cULus, and CE standards, ensuring the part satisfies local code requirements for industrial process controls.

Common Questions

What is the maximum temperature the sensor can withstand?
The sensor is designed to withstand a maximum temperature of 200°C (392°F), ensuring the charge in the remote bulb remains stable even during slight system overshoots.

Can this be used for cooling applications?
The KP81 features SPDT contacts (Single Pole Double Throw), meaning it can be wired to either break or make a circuit on temperature rise. However, as a manual reset "Max" control, it is specifically optimized for high-limit heating cutouts.

What is the purpose of the 9°C fixed differential?
The fixed differential ensures a consistent gap between the trip point and the point at which the system can be manually reset, preventing premature restarts before the system has sufficiently cooled.
