HCET-A Series TB02 Bimetal Thermal Protection Switch High Precision Thermal Cutout Switch for Transformers

HCET-A TB02 is a high-quality thermal protection switch designed for transformers. It adopts bimetal sensing technology and monitors the operating status of the equipment in real time through temperature-sensitive components. When the transformer is overheated due to overload, short circuit or abnormal ambient temperature, the switch automatically triggers and cuts off the circuit, preventing equipment damage or safety accidents. The product is suitable for power transformers, voltage regulators, industrial power supplies and other scenarios, providing accurate temperature control and overheating protection dual function, in line with IEC, UL and other international safety standards.

• Precise bimetal temperature control - Built-in high sensitivity bimetal, response speed ≤ 5 seconds, temperature control accuracy ± 3°C, support wide temperature range customization (30°C - 155°C), to meet the needs of transformers in different working conditions.
• Reliable overheating protection - Integrated thermal protection switch function, when the temperature exceeds the limit, instantaneous power failure, to avoid overheating transformer coil burnt or insulation failure, to protect the equipment and personnel safety.
• Industrial durability - The shell is made of high temperature resistant and corrosion resistant metal shell, the contacts are silver-plated to support high loads, with a service life of more than 30,000 cycles, adapting to harsh industrial environments.
• Safety certification guarantee - UL, CE, RoHS certified, meets the fire protection and environmental protection requirements for electrical equipment, ensuring global market compliance.
• Convenient Mounting Design - Standard terminal blocks or bolt-on options are available. Compact design (dimensions can be customized) fits all types of transformer mounting spaces, and maintenance is simple and low-cost.
