The TH330IoT is an industrial control panel that integrates the TH104IoT V6.1 (thermal protection) and TH212IoT V3.1 (ventilation protection) controllers in a single cabinet, offering a complete solution for temperature monitoring and automatic fan activation. Ideal for dry transformers, the system combines protection, automation, and IoT connectivity with ease of installation and maintenance.

The IP65 version of the TH330IoT was developed for applications in areas exposed to dust and water splashes, ensuring robustness and reliability even in adverse conditions.

The TH330IoT is assembled with terminal blocks for electrical connections, ½” cable glands for PT100 probe input, and Sealtube fastening input for electrical cabling. It also has a 10A C-curve protection circuit breaker for the fans, ensuring safety and practicality in the field.
