The NTK Oxygen Sensors 5049-120 is a high-capacity 120 amp circuit breaker designed to provide reliable overcurrent protection for automotive, marine, RV, and powersports electrical systems. This thermal circuit breaker automatically trips when current exceeds its 120 amp rating, protecting wiring and components from damage due to electrical overload or short circuits.

Key Features:

• 120 amp current rating for high-load applications
• Automatic reset capability protects against overcurrent conditions
• Thermal trip mechanism for reliable circuit protection
• Compact design for easy installation in tight spaces
• Durable construction for harsh automotive and marine environments
• Suitable for DC electrical systems in vehicles, boats, and RVs

This circuit breaker is ideal for protecting high-draw accessories such as winches, inverters, audio systems, and other power-hungry equipment. The automatic reset feature allows the breaker to be reused after it cools down and the fault condition is cleared, eliminating the need for fuse replacement.
