- 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.
- Controls the temperature of the motor room (relay + external module OD-T2) or the temperature inside switchboards where no motor room is present. (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.
Phase and Temperature (PTC) Relay
- 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 ruptured wire in PTC circuit.
