Overload relay type TR2-D are 3 Pole, manual/ auto reset type, providing protection against overload, single phasing & unbalance voltages. They are primarily direct mounting on compatible T Range contactors & with independent mounting kit can be converted to individual mounting relays. They are available in relay setting range from 0.10 to 93A direct operated in 24 options of relay range to fully protect the electric drives. They fully meet the requirements of IEC 947-4-1 & IS 13947-4-1.
Superior Class 10 characteristics
Class 10 overloads like TR2-D series have been recognized by many motor manufacturers as the ideal type to assure optimum protection for today's T-frame motors.
Single phase protection
A unique deferential slide mechanism assures accelerated tripping under single phase conditions & unbalanced voltages.
Ambient temperature compensation
All TR2-D series thermal overload relays are temperature compensated to ensure that tripping characteristics remain constant over an ambient range of -40 to +60 degrees C
Control Circuit
All TR2-D series overload relays have two independent, polarity free, I NO & 1 NC control contacts. |
