The ABB TF65-60 is a thermal overload relay designed to protect electric motors against sustained overcurrent and phase loss conditions. With an adjustable current setting range of 50–60 A and a rated insulation voltage of 690 V, this relay is engineered for demanding industrial and marine electrical systems. Onboard vessels, thermal overload relays are critical components in motor control centres (MCCs), protecting pumps, fans, compressors, winches, and other essential auxiliary machinery from thermal damage. Reliable motor protection directly supports vessel uptime, crew safety, and regulatory compliance.
Key Features
✓ Adjustable thermal current range of 50–60 A for flexible motor matching
✓ Rated insulation voltage of 690 V (UI) with 8 kV impulse withstand (UIMP)
✓ Short-circuit withstand capacity of 100 kA RMS symmetrical at up to 600 V AC
✓ Integrated auxiliary contacts for alarm and trip signalling to control and monitoring systems
✓ Compact DIN-rail or contactor-mount design for straightforward panel integration
Marine Applications
Motor protection in engine room ventilation fan starters and associated MCCs
Overload protection for ballast, bilge, cooling water, and fire pump motor circuits
Thermal relay duty in HVAC compressor and air handling unit motor starters
Protection of deck machinery drives including winch and crane motor feeders
Safeguarding auxiliary generator and workshop machinery motor control circuits
