3AXD50000049451 ABB R172GA-051-D0550 NMB High-performance Servo Fan DC24V
The ABB R172GA-051-D0550 is a high-precision bimetallic thermal overload relay from ABB’s trusted TA75DU series, designed to protect electric motors against overload, phase loss, and phase imbalance in industrial and commercial applications. With an adjustable current setting range of 0.10–0.16 A, this compact relay is ideal for safeguarding small fractional-horsepower motors used in HVAC systems, pumps, conveyors, compressors, and automation equipment.
Key Features & Benefits
Precise Low-Current Protection (0.10–0.16 A)
Specifically calibrated for small motors (typically <0.1 kW / 0.13 HP at 230V)
Prevents insulation damage and premature motor failure due to sustained overloads
Plug-and-Play Mounting on ABB Contactors
Snap-on design fits ABB A9, A16, AF09–AF16 contactors without adapters
Saves panel space and reduces wiring complexity
Built-In Auxiliary Contacts for Control & Monitoring
1 Normally Closed (NC) contact for breaking the coil circuit during trip
1 Normally Open (NO) contact for alarm, PLC input, or remote indication
Eliminates need for external signaling modules
