CHARACTERISTICS
Nominal frequency 50/60 Hz
Control range
Maximum temperature
from 40˚C to 55˚C.
Maximum temperature
from -5˚C to 5˚C.
Phase loss: with resistive loads it trips when a
phase loss occurs. With three-phase motors it trips
if the voltage regenerated by the motor is lower than
60% of the main voltage. Phase imbalance > 40%.
Maximum temperature setting from 40 ºC a 55 ºC.
Minimum temperature setting from -5 ºC a 5 ºC.

WORK LOGIC
TST-24T
Controls the temperature of the motor room (relay + external
module OD-T2) or the temperature inside the switchboards where
there is no motor room (relay + internal sensor IN-T2).
Designed according to the EN 81-1 standard and complying with
the European Union Directive for Lifts (95/16/CE).
• Two adjustable temperature thresholds.
Protection relay against variations of the ambient temperature
(min/max), overtemperature of the motor, phase sequence and
phase imbalance or phase loss.
• DIN rail mounting.
• Visual indication of trip cause.
To Protect 3-phase devices.
Suitable for Motors with built-in PTC sensors in applications such
as elevators, cranes, hoists and similar installations.
• Sensitive to incorrect phase sequence.
• Monitoring of short circuit and broken wire in PTC circuit.
