Description
The Schneider Electric (Barber Colman) TA-3441 is a heavy-duty duct and immersion thermostat engineered for low limit freeze protection in commercial and industrial HVAC air handling systems. Designed to open on a temperature drop, this SPST control reliably safeguards coils, ductwork, and air handling equipment from freezing conditions, triggering a manual reset that requires deliberate operator intervention before the system can resume operation — preventing accidental restart before the root cause is addressed.
Key Features
- Low limit control action: SPST opens on temperature drop to protect against freeze conditions
- Setpoint range: 35°F to 59°F — ideal for freeze protection applications
- Fixed differential: 10°F for consistent, predictable switching performance
- Manual reset: requires deliberate reset after a low-limit trip event
- Dual voltage compatibility: rated for 120V and 240V applications
- Insertion length: 1/2″ x 7-1/2″ for duct or immersion mounting
- NEMA 1 enclosure: suitable for general-purpose indoor installations

Application
The TA-3441 is well-suited for use in air handling units, mixed-air plenums, and hydronic coil applications where freeze protection is critical. Its manual reset design ensures that maintenance personnel must physically inspect and clear the fault condition before restoring system operation, adding an important layer of safety in commercial building environments.
