T-RST

Phase control relay with thermistor motor protection
• Detects phase failure, phase sequence, and thermistor motor protection.
• Monitors its own supply voltage.
• Does not detect phase failure with regenerated voltage present (back EMF).
• Measuring voltage with/without neutral.
• LED indicates for: relay status, thermistor failure, and sequence.
• Remote reset available.
• Up to 6 PTC sensors in series.
