Working Mechanism

  • They work by interrupting the flow of electrical current when it exceeds a preset limit.
  • These circuit breakers consist of a bimetallic strip that bends when exposed to excessive current, causing it to trip and open the circuit.
  • This interruption prevents further damage to the vehicle's electrical system and accessories.

Features

  • These circuit breakers feature a flush mount design for seamless integration into the vehicle's electrical system.
  • They come equipped with a convenient push-to-trip button, allowing for easy manual resetting in the event of overcurrent issues.
  • These circuit breakers also include 1/4-28 threaded studs for easy installation and provide secure attachment points for wiring connections.
  • They have waterproof and sealed housing that ensures reliable performance even in challenging environmental conditions, preventing water and dust ingress for long-lasting durability.
  • These Bussmann automotive circuit breakers include SEMS nuts for further streamlining installation and ensuring a secure and reliable connection.
  • They feature thermoplastic construction for enhanced durability and resilience in automotive environments.

Frequently Asked Questions

How do I install these automotive circuit breakers?
