Relay temperature control FANOX ST y ST-D

Suitable for motors with built-in PTC sensors in applications such as elevators, cranes, hoists and similar installations.

• Protection against phase imbalance, phase loss, phase sequence and overtemperature.
• To protect three phase devices.
• Monitoring of short circuit and broken wire in PTC circuit.
• Self-powered by voltage to be monitored.
• Visual indication of tripping cause.
• DIN rail mounting.

*ST-D Model: 2 output relays, one for phase imbalance, phase loss and phase sequence and the other for overtemperature.
