Phase monitoring relay tcp sf 3 x 200 440 vac hiquel tcp sf phase monitoring relay
The tcp sf with 1 co contact monitors the correct phase sequence l1 l2 l3 clockwise and loss of any phase it is used in three phase installations where the motor direction depends on the phase sequence to protect them against damage a major advantage of this unit is the nominal voltage the device works from 3 x 200 to 440 vac zoom voltage mounts onto din rail en50022
