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%

• Self-powered by the voltage to be monitored.
• Visual indication of trip cause.
• DIN rail mounting.
• 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.
ST-D model:
Two output relays, one for phase imbalance, phase loss and
phase sequence and the other for over temperature.
Two output relays, one for phase imbalance, phase loss and
