Description

TCP-M-3-400VAC HIQUEL Phase failure relay

The TCP-M-3-400VAC HIQUEL phase failure relay is used for phase failure and thermistor protection. Hiquel’s TCP-M monitors phase sequence, phase failure and phase asymmetry, and is used with PTC sensors to provide over temperature protection for motors and other equipment. When the phase sequence is correct, all phases are detected, and the resistance of the PTC sensors on the input T1 – T2 is within the correct range, the output relay R energises. At a loss of one phase (> Vn x 0.75 ), or the detection of an asymmetry imbalance >10%, or when the resistance of the PTC sensors exceeds the triggering threshold (3100 Ohm) the reaction time starts.

Features:

• detects phase failure, phase sequence phase asymmetry and over-temperature using PTC sensors
• detects phase failure with regenerated voltage present DPCO output max. 6A
• up to 6 PTC sensors in series
• fixed asymmetry alarm >10%
• no neutral connection required
• adjustable reaction timer 0.1 – 10s
• LED indicators for power supply, relay and reaction timer
• 45mm DIN rail mount housing
