Product Details

The NTK 5049-40 is a 40-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 rated capacity, protecting wiring and electrical components from damage due to overload or short circuit conditions.

Key Features:

  • 40-amp current rating for medium to heavy-duty electrical circuits
  • Automatic reset or manual reset design (depending on model configuration)
  • Thermal trip mechanism for consistent, reliable protection
  • Compact design for easy installation in tight spaces
  • Suitable for 12V and 24V DC systems
  • Durable construction for harsh automotive and marine environments

This circuit breaker serves as a reusable alternative to traditional fuses, eliminating the need for replacement after each trip event. Ideal for protecting high-current accessories such as winches, lighting systems, audio equipment, and other power-hungry electrical components.

Smooth transaction . Got it a day later but received it . Paid extra for early delivery which didn't happen
