LVR055 PTC Resettable Fuse 240V 550mA Through Hole
The PolySwitch line-voltage-rated (LVR) devices help protect electric motors and transformers used in commercial and home appliances from damage caused by mechanical overloads, overheating, stall, lost neutral and other potentially harmful conditions. The LVR line-voltage product line of polymeric positive temperature coefficient (PPTC) devices includes components that are rated for line voltages of 120VAC, VDC and 240VAC, VDC for up to 2A of operating current at 20°C. They help protect against damage caused by both overcurrent surges and overtemperature faults.
Features
- Current rating of 550mA
- Line voltage rating 240VAC, VDC
- Fast time-to-trip
- Low resistance
