Indeeco 1006389 324F Manual Reset High Limit Control, 144″ Capillary

Indeeco 1006389 — 324°F Manual Reset High Limit Control

The Indeeco 1006389 is a manual reset (M/R) high limit control designed to provide dependable overheat protection for electric duct heaters and industrial heating systems. Rated at a 324°F setpoint and equipped with a 144-inch (12-foot) capillary tube, this control offers the sensing reach needed for larger heater assemblies and extended duct runs.

Key Features

• Manual reset operation — requires deliberate operator action to restore power after a high-limit trip, preventing automatic restart after an overheat event
• 324°F (162°C) high-limit setpoint for precise overheat protection
• 144-inch (12-foot) capillary tube for extended sensing range across large heating elements or duct sections
• Designed as a direct OEM replacement for Indeeco electric duct heaters
• Helps protect heating elements, ductwork, and connected equipment from damage due to overtemperature conditions
• Durable construction suited for demanding commercial and industrial HVAC applications

Application

This high limit control is a critical safety component in electric duct heater installations. When duct air temperature exceeds the rated setpoint, the control interrupts the heating circuit and requires a manual reset before the heater can resume operation — ensuring that the root cause of the overtemperature condition is identified and corrected before restart. It is an ideal OEM replacement part for Indeeco electric duct heater units.
