NTK Oxygen Sensors 5049-100 Circuit Breaker 100 Amp

The NTK 5049-100 is a 100-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 overloads or short circuits.

Key Features:

• 100-amp continuous current rating for high-capacity circuits
• Automatic reset or manual reset functionality (varies by model)
• Thermal overcurrent protection mechanism
• Compact design for easy installation in tight spaces
• Corrosion-resistant construction suitable for harsh environments
• Standard stud or surface mount configuration

This circuit breaker is commonly used in battery management systems, inverter circuits, winch installations, and high-amperage accessory circuits. It provides a reusable alternative to traditional fuses, allowing quick circuit restoration after an overload condition is resolved.
