Fanox Control Measurement Relay ST4-D

Fanox provides advanced protection solutions for motors with built-in PTC (Positive Temperature Coefficient) sensors, particularly suited for applications such as elevators, cranes, hoists, and similar installations. These protection devices are designed to ensure safe and efficient operation by monitoring critical parameters and providing comprehensive protection against various electrical faults. Here are the key features and specifications of these devices:

Key Features:

1. Protection Against Phase Imbalance and Phase Loss:

   • Ensures Balanced Operation: Detects and protects against phase imbalances and phase loss, preventing potential damage to the motor.

2. Protection Against Overtemperature:

   • Temperature Monitoring: Monitors the motor's temperature using built-in PTC sensors and trips the motor in case of overtemperature conditions to prevent overheating.

3. Phase Sequence Protection:

   • Correct Phase Order: Ensures the correct phase sequence, preventing damage caused by incorrect phase wiring.

4. Monitoring of PTC Circuit:

   • Short Circuit and Broken Wire Detection: Monitors the PTC circuit for short circuits and broken wires, ensuring the integrity of the temperature monitoring system.

5. Self-Powered by Voltage to be Monitored:

   • No External Power Supply Needed: The device is self-powered by the voltage it monitors, simplifying installation and reducing the need for additional power sources.

6. Visual Indication of Tripping Cause:

   • Easy Diagnostics: Provides clear visual indicators to quickly identify the cause of a trip, facilitating troubleshooting and reducing downtime.

7. DIN Rail Mounting:

   • Ease of Installation: Designed for easy and secure mounting on standard DIN rails, making installation straightforward and space-efficient.
