TH-T50KP Thermal Relay for Motor Protection

In the face of three-phase motors that drive the core of production lines, large fans, or heavy-duty pumping stations, universal protection settings often fall short. The SPX high quality TH-T50KP Thermal Relay for Motor Protection is a professional level protection center designed to address such challenges. It breaks away from the fixed specification protection mindset and provides a wide range, finely adjustable protection platform. Engineers can set the most personalized protection parameters for each motor based on its unique "fingerprint" (rated current, starting characteristics, environmental conditions), just like calibrating precision instruments. This design concept transforms it from a passive "fault responder" to an active "operation adapter" when protecting medium-sized and above motors.
The TH-T50KP Thermal Relay for Motor Protection in stock is based on the T50 framework, and its adjustable current range covers a wider range of medium and high current segments, allowing users to set it continuously and accurately within a wide range (such as by replacing the thermal element or adjusting the knob) according to the motor nameplate current, achieving high cost-effectiveness and flexible configuration of "one machine, multiple uses".
In response to the greater harm caused by phase failure operation of medium-sized motors, the TH-T50KP Thermal Relay for Motor Protection adopts an optimized differential amplification mechanism internally, which is extremely sensitive to three-phase current imbalance and can significantly accelerate the tripping response, providing faster phase failure protection for the motor.
Built in high-performance temperature compensation bimetallic strip can effectively counteract the impact of environmental temperature changes on protection characteristics, ensuring that the protection action curve remains stable and consistent regardless of whether it is in cold outdoor or high-temperature workshop environments, avoiding seasonal misoperation or refusal to move.
Equipped with large and prominent manual reset buttons/knobs, trip indicator signs, and action observation windows, it can quickly identify its working status even in complex distribution cabinets.
Usually, multiple independent normally open and normally closed auxiliary contacts are provided. In addition to controlling circuit tripping, fault signals and operating status can be seamlessly integrated into PLC or remote monitoring systems to achieve the integration of protection and monitoring.

Overload and phase failure protection for large water pumps, fans, air compressors, and conveyor drive motors.
Equipment such as mixers, crushers, extruders, etc. that have heavy load start-up or large load fluctuations.
TH-T50KP Thermal Relay for Motor Protection is used as motor protection for water treatment pump stations, cooling tower fans, and large HVAC system hosts.
