ABB DSQC 327 3HAB 7230-1
Product Description: The ABB DSQC 327 3HAB 7230-1 is a three-phase phase sequence control relay designed to protect three-phase motors against damage caused by incorrect phase sequence, phase shift or phase loss.
Features:
Rated voltage: 208-690 V AC, 50/60 Hz
Nominal current: 5 A
Number of contacts: 2 (1NO, 1NC)
Response time: 20 ms
Operating temperature range: -25°C to +70°C
Connection: Screw terminal
Mounting: On DIN rail
Certifications: IEC/EN 60255, UL 508, CSA C22.2 No.14
Display: LEDs indicated for each phase (L1, L2, L3)
Manual reset button
IP protection: IP20
Operation: The relay monitors the voltage and phase sequence of the electrical system. If an incorrect phase sequence, phase shift or loss of phase is detected, the relay opens the NO (normally open) contact and closes the NC (normally closed) contact. This disconnects the protected motor, preventing potential damage.
Applications: ABB DSQC 327 3HAB 7230-1 is used in various industrial and commercial applications including:
Protection of three-phase motors
Pump control systems
Conveyors
Air compressors
Ventilation systems
Benefits:
Reliable protection against engine damage
Easy installation and wiring
Compact dimensions to save space
Reduced maintenance costs and downtime
