NTK Oxygen Sensors 5049-80 Circuit Breaker 80 Amp

The NTK Oxygen Sensors 5049-80 is an 80 amp circuit breaker designed to provide reliable overcurrent protection for electrical systems in automotive, marine, RV, and powersports applications. This thermal circuit breaker automatically trips when current exceeds its rated capacity, protecting wiring and components from damage due to electrical overload or short circuits.

Key Features:

• 80 amp current rating for high-load circuits
• Automatic reset thermal breaker design
• Compact construction for easy installation in tight spaces
• Durable construction withstands vibration and harsh environments
• Provides overcurrent protection without the need for fuse replacement

This circuit breaker is ideal for protecting high-amperage circuits such as winches, inverters, battery charging systems, and other high-draw electrical accessories. The thermal design allows the breaker to automatically reset once the fault condition is cleared and the breaker cools down, eliminating the need for fuse replacement and reducing downtime.
