Thermal Protection Relay

The HVEX Thermal Relay is an advanced solution for the protection and monitoring of transformers, electrical panels, and power systems, ensuring high reliability and performance. Designed for temperature and current measurement, the device provides safety and precision in critical power generation, transmission, and distribution applications. With configurable measurement channels, the relay allows alarm and trip settings for intelligent thermal protection. Its thermal protection relay features Modbus TCP/IP, DNP 3.0, Bluetooth, and optional Wi-Fi communication, enabling remote supervision and parameterization. Additionally, a non-volatile memory card records events, measurement history, and programming, ensuring traceability and operational reliability. Key features include: • Complete protection for dry-type transformers, oil transformers, and electrical panels. • Accurate current and temperature measurement with less than 0.5% uncertainty. • Modular plug-and-play connection and DIN 35 mm rail mounting. • High resistance to overloads and shielding against external magnetic fields. • Local interface for real-time monitoring of measured values. The HVEX Thermal Relay complies with major national and international standards such as IEC 60255 and NBR IEC 60529, offering safety and regulatory compliance. With this technology, your company ensures enhanced protection, monitoring, and energy efficiency, reducing unexpected failures, optimizing predictive maintenance, and extending the lifespan of critical assets.
