Product Details

The Blue Sea Systems 7141 is a 70-amp thermal circuit breaker from the 187 Series, designed for surface mount installation in marine DC electrical systems. This switchable circuit breaker combines circuit protection and switching functionality into a single robust device, eliminating the need for separate components.

Key Features:

  • Trip-free design prevents the breaker from being held in the "ON" position during fault conditions, ensuring automatic protection
  • Clear single-lever operation with vertical/horizontal orientation provides visual indication of trip status
  • Ignition protected construction meets SAE J1171 external ignition protection requirements—safe for gasoline-powered boats
  • Waterproof housing protects internal components from harsh marine environments
  • Recessed mounting holes create a clean, professional appearance
  • Robust 5/16-inch terminal studs provide high-torque connections with ample clearance for heavy gauge wire lugs
  • Thermoset polyester case material ensures durability and chemical resistance

Technical Specifications:

  • Rating: 70 Amps
  • Circuit Breaker Class: Type III - Switchable/Manual Reset, Trip Free
  • Breaker Type: Thermally responsive bi-metal blade
  • Voltage Rating: 48 Volts DC maximum
  • Interrupt Rating: 5,000 Amperes at 12V DC, 3,000 Amperes at 24V DC, 1,500 Amperes at 42V DC
  • Operating Temperature Range: -25°C to +82°C (-13°F to 180°F)
  • Mounting Style: Surface mount

Ideal for protecting high-current DC circuits on boats, RVs, and other marine or mobile applications where reliable overcurrent protection and switching control are essential.

AT THIS TIME &quot;GREAT TRANSACTION&quot;

Great price!!

Easy to navigate web site

Allways been easy to order, quick shipping also.

Only downside is I couldn't use multiple coupons - one for shipping discount and another for 10% off.

Purchased set of four Scribner 5 gallon utility jug. After doing considerable looking, Autoplicity had the lowest price by far in comparison to all other competitors. Communication has been great with items ordered shipped with tracking number the next day. Great buying experience.

Easy to use, great prices and fast delivery too

They have it nailed down....instant email updates, great pricing, and dirt cheap shipping. I'm hooked.

Best price

Thanks

Great prices, reasonable shipping costs. Shipped within 3 days of order. Didn't receive discount for valid coupon code (25OffShipping). No response to 2 emails. No indication of expected delivery date. Lots of unknowns but you can't beat the pricing.

Great Seller. Fast Shipping and great prices!

Autoplicity is the place to go! I was in the market for a reusable K&N Air Filter and Autoplicity had the best price around (with shipping and handling). My order was filled and shipped promptly, arrived on time, and in perfect condition. Autoplicity kept me up to date with the status of my order at all times until it arrived. I would purchase from Autoplicity again. <br>
