TH-T65 54A Thermal Relay

In the field of motor protection, a universal protection range is often difficult to achieve optimal matching. The high-quality TH-T65 54A Thermal Relay researched by SPX breaks this limitation. It is not a broad current adjustable device, but a specialized protection device that has been deeply optimized for typical 54A application scenarios in advance. Its core value lies in precise thermal and mechanical calibration around the 54A center point at the factory, providing reliable protection for motors with rated currents near this point without frequent debugging, higher matching, and more consistent action. It is particularly suitable for the selection needs of standardized equipment manufacturing and batch applications.
During the design and manufacturing of high quality TH-T65 54A Thermal Relay, the heating characteristics, deformation parameters, and tripping mechanism of the bimetallic strip are synergistically optimized using 54A as the reference point to ensure that the protection characteristic curve (such as start-up time and tripping time) near this current point is in the optimal state.
Compared to large-scale adjustable relays, the TH-T65 54A Thermal Relay in stock with fixed-point calibration can provide higher product consistency and protection action repeatability in batch applications, reducing protection performance fluctuations caused by differences in on-site debugging.
The thermal capacity and heat dissipation design of the TH-T65 54A Thermal Relay thermal element is specifically designed to simulate the heat accumulation and cooling process of motors of this power level, which can more accurately reflect the temperature rise of the motor winding and prevent false protection or insufficient protection under frequent start stop or intermittent overload conditions.

Application:

Overload protection for centrifugal pumps and circulating pumps ranging from 22kW to 30kW.
Power protection for medium-sized fans, cooling tower motors, and air conditioning units.
Standard protection unit for motors driving medium-sized conveyor belts and elevators.
TH-T65 54A Thermal Relay is a designated protective accessory for OEM equipment manufacturers on their standard models (such as specific models of packaging machines and mixers), ensuring consistent protection performance for batches of products.
