Indeeco 1006953 Limit

The Indeeco 1006953 is a precision-engineered bimetal manual reset cutout limit designed for critical over-temperature protection in industrial heating systems and heavy-duty HVACR applications. As a direct cross-reference for part C242-17, this high-limit switch is calibrated to open at a fixed temperature of 200°F, effectively breaking the circuit to prevent catastrophic equipment failure or fire hazards due to overheating. The manual reset requirement is a vital safety feature for contractors, ensuring that a professional technician must inspect the system and identify the root cause of the thermal excursion before the equipment can be returned to service. Built with a rugged bimetal sensing element, the Indeeco 1006953 limit switch offers superior thermal response times and vibration resistance, making it an ideal OEM replacement for duct heaters, unit heaters, and commercial furnace assemblies requiring high-limit safety controls.

Key Benefits for Technicians

• Universal Cross-Compatibility: Direct replacement for C242-17, ensuring seamless mechanical and electrical fitment in existing control circuits.
• High-Temperature Precision: Factory-set to trip at 200 degrees Fahrenheit for accurate high-limit thermal protection.
• Manual Reset Safety: Prevents dangerous short-cycling by requiring manual intervention after a high-limit event occurs.
• Industrial-Grade Build: Constructed with durable materials to withstand the high-ambient environments of industrial heat treat and HVAC plenum applications.
• Critical Protection: Safeguards expensive heating elements and prevents potential damage to downstream ductwork and components.

Common Questions

Is the 1006953 a direct replacement for the C242-17?
Yes, the Indeeco 1006953 is the industry-standard cross for the C242-17 manual cut out limit, maintaining the same 200°F trip point and mounting configuration.

Can this limit switch be used in 24V or 120V circuits?
This manual reset limit is designed to interface with standard control circuits; however, you must verify that the amperage draw of your specific contactor or load does not exceed the switch's electrical rating.

Why is my Indeeco limit tripping?
A trip at 200°F typically indicates restricted airflow, a failed blower motor, or an oversized heating element. The manual reset ensures the HVAC high limit is not bypassed until the airflow issue is resolved.
