Product Details

The Blue Sea Systems 7144 is a 100-amp thermal circuit breaker from the 187-Series, designed for surface mount installation in marine DC electrical systems. This single-pole breaker combines circuit protection and switching functionality into one rugged, waterproof device, making it ideal for protecting high-current circuits on boats, RVs, and other 12-48V DC applications.

Key Features:

  • 100 amp rating with thermally responsive bi-metal blade design
  • Trip-free operation prevents holding switch "ON" during fault conditions
  • Waterproof construction with thermoset polyester case
  • SAE J1171 ignition protection certified - safe for gasoline-powered vessels
  • Robust 5/16" terminal studs with high torque capacity for secure connections
  • Recessed mounting holes for clean, professional installation
  • Large single lever with clear ON/OFF indication and trip status visibility
  • Rated for 48 volts DC maximum with interrupt ratings up to 5,000 amps at 12V

Technical Specifications:

  • Circuit Breaker Class: Type III - Switchable/Manual Reset
  • Voltage Rating: 12-48 VDC maximum
  • Interrupt Rating: 5,000A @ 12VDC, 3,000A @ 24VDC, 1,500A @ 42VDC
  • Operating Temperature: -25°C to +82°C (-13°F to 180°F)
  • Terminal Size: 5/16" studs accommodate large gauge wire lugs

This circuit breaker provides reliable overcurrent protection while eliminating the need for separate switches in your electrical system. The vertical/horizontal lever orientation and trip-free design ensure safe operation even under fault conditions.

First off, I LOVE my new shipments! These guys had everything at super low prices, and the shipping was phenomenally fast. It's all working great, and imm definitely buying from these guys again.

Thanks

I was very impressed by Autoplicity's customer service and excellent pricing on brand name products. Also, they provided lightning fast shipping even as the holiday weekend approached.<br>As much as I want to see everyone in this world to "live long and prosper," I was especially pleased to deal with a company that did not export their customer service to another country. <br>I look forward to doing business again with Autoplicity.
