PHASE and TEMPERATURE control relays (Lifts)

• 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.
Temperature control
• 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.
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 broken wire in PTC circuit.
