Thermal Overload Relays TR series General information
Standard type thermal overload relays Description Highly reliable thermal overload relays FUJI thermal overload relays are designed to provide overload protection to meet the thermal characteristics of low voltage induction motors. Adjustable thermal overload relays give motors positive overcurrent protection. The starter contacts cannot be held closing under overload conditions. However, once the bimetal element has cooled, the reset button can be depressed and the motor can be restarted in the normal manner. Ordinarily this reset is carried out manually but the starter can be changed over to ‘automatic reset’ by means of a screw-driver. • FUJI thermal overload relay is subjected to stringent testing in the factory to check performance and actual values are calibrated with the markings on the adjustable dial. Consequently, they provide a positive protection. • Relays are also provided with ambient temperature compensators, so that their performance will be maintained in spite of temperature changes. The ambient temperature is regulated for 20°C. • The heater elements are available for either 2- or 3-pole use. ■
•
Long time operating type In the case of loads having large inertia moments such as blowers, winders or centrifuges the starting time is extended. This will cause the standard-type thermal overload relay to operate during starting so isolating the motor. If necessary FUJI will supply thermal relays with saturable reactors. (Timedelay type). Quick operating type overload relays The windings of submersible pump and compressor motors normally have a smaller overload capacity than those of standard motors, since they are generally cooled by the water and other medium being pumped. Q type overload relays will operate more quickly than the standard type in the face of a locked rotor current.

Features Isolated NO and NC contacts can be used with different potentials. Gold-flashed silver contact assures high contact reliability (TR-0N/3 to N14/3). Stable operating characteristics protect motors from burnout due to overload or locked rotor currents. Easy setting of current value with a calibrated dial. Both manual and auto reset available. A manual trip button is provided to facilitate sequence testing. Mechanical trip indication Trip-free mechanism is provided. Reset release button and trip indicator are optional accessories.

■ Warning All FUJI thermal overload relays have been tested and calibrated at the factory. They should not be tampered with or stripped down at the job site since this would affect their accuracy. A special feature of the FUJI starter series is the ease by which the relay current ratings can be varied to match the requirements of the load. The changeover is effected by simply turning a dial to the new value required. The range of adjustment is approximately 100%–125%–150% and details are given overleaf.

Thermal Overload Relays TR series
Features Manual trip These relays can be manually tripped for sequence inspection by pressing manual trip bar (TR-0N/3, TR-5-1N/3). A sequence inspection will be performed when the test button is pulled out. When the test button is pressed in, only the NC contact will turn OFF. The original status will be restored when the test button is then released.(TR-N2/3 to N8/3) ■ ●
Trip-free mechanism Even if the reset button is carelessly pressed, this relay trips without trouble (Trip-free mechanism).

Thermal Overload Relays TK series With phase-loss protective device
Thermal overload relays with phase-loss protective device Description
FUJI TK series consists of a 3-heater element thermal overload relay and an phase-loss protective device. These two elements are assembled to make the relay unit. The overload relay characteristics are designed to meet the thermal characteristics of a squirrelcage motors at the time of overload. A FUJI ADL mechanism is also provided to protect from phase-loss. This ADL mechanism is incorporated with the overload relay. The characteristics are coordinated with the temperature rise curve in stator winding at the time of motor phase-loss. They respond quickly to overloads. Other features include the following.
Characteristics
The operating characteristics of a thermal overload relays represents its tripping time and response current starting from cold or hot state. Standard
IEC 105% Ie 60947-4-1
120% Ie (2h max.)
Hot starting characteristics
In cold starting, tripping time is measured from the time when the temperature of the thermal overload relay is equal to the ambient temperature.
In hot starting, tripping time is measured from the time when the thermal overload relay reaches the steady state after non-tripping current flows two hours.
When all poles are not equally energized Operating limit Non-tripping
