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-type transformers, the system combines protection, automation, and IoT connectivity with ease of installation and maintenance.

The IP50 version of the TH330IoT is designed for applications in controlled environments, offering a practical and standardized solution for thermal protection and fan activation in dry-type transformers.

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.
