The CN3261 Series high-limit controller protects expensive heaters and sensitive materials from damaging due to temperature conditions. Units are designed for industrial and commercial applications that require hightemperature protection. The CN3261 features a Form “C” latching, manually resettable relay output that de-energizes whenever the sensed temperature exceeds the setpoint temperature.Two methods are provided to reset an alarm condition, 1, the limit alarm has a reset pushbutton on the unit and 2, reset terminals are provided for resetting the alarm from a remote pushbutton. The DIN rail mounting feature allows quick installation without drilling or extra hardware. Slots are also provided for direct panel mounting.
