Its surface mount design with front terminal studs simplifies installation, while water resistance and a 5-year warranty ensure reliable, long-lasting circuit protection. ## Description Circuit protection and switch combined in a single medium duty breaker. Ideal for windlass and electric winch applications, these surface mounted medium duty circuit breakers function as a switch, but also provide tailored circuit protection. A visible lever shows when the breaker has tripped and cannot be held in the ON position if a fault is detected. Ignition protected and water resistant, they can be installed almost anywhere; including the engine room of gasoline powered boats. Connected terminal caps protect terminals from accidental contact and help to prevent cross current shorts. Terminal studs are located on the face of the circuit breaker for easy installation. ## Features - Combine switching and circuit protection into single switch - Drop in replacement for 185 series circuit breakers - Trip-Free feature means switch cannot be held in ON position when a fault is detected - Ignition protected; can be installed in engine rooms of gasoline powered boats - Five-year warranty ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0051OWRHE | | Best Sellers Rank | #8,451 in Automotive ( See Top 100 in Automotive ) #12 in Automotive Replacement Circuit Breaker Switches | | Brand Name | Blue Sea Systems | | Circuit Breaker Type | Standard circuit breaker | | Current Rating | 150 A | | Customer Reviews | 4.6 4.6 out of 5 stars (184) | | Global Trade Identification Number | 00632085071899 | | Included Components | Great Product | | Item Type Name | Great Product | | Item Weight | 5.6 ounces | | Manufacturer | Blue Sea Systems | | Model | 7189 | | Mounting Type | Surface Mount | | Number of Items | 1 | | Number of Poles | 1 | | Part Number | 7189-BSS | | UPC | 632085071899 | | Unit Count | 1 Count | | Voltage | 48 volts_of_direct_current | | Warranty Description | Warranty | ## Product Details - **Brand:** Blue Sea Systems - **Circuit Breaker Type:** Standard circuit breaker - **Current Rating:** 150 A - **Mounting Type:** Surface Mount - **Number Of Poles:** 1 ## Images ![Blue Sea Systems 7189 285 Series Thermal Circuit Breakers, Surface Mount, 48V DC, 150A - Image 1](https://m.media-amazon.com/images/I/51S1D2ZzsEL.jpg) ![Blue Sea Systems 7189 285 Series Thermal Circuit Breakers, Surface Mount, 48V DC, 150A - Image 2](https://m.media-amazon.com/images/I/31zWdMDOgJL.jpg) ![Blue Sea Systems 7189 285 Series Thermal Circuit Breakers, Surface Mount, 48V DC, 150A - Image 3](https://m.media-amazon.com/images/I/61Uyvdm1O8L.jpg) ## Available Options This product comes in different **Pattern, Color, Style** options. ## Frequently Bought Together - Blue Sea Systems 7189 285 Series Circuit Breaker, Surface Mount, 150 Amp, 48V DC - Blue Sea Systems 5026 ST Blade Fuse Block 12 Circuit with Ground and Cover - 10 Gauge Marine Wire,10 AWG 30ft Duplex Marine Grade Wire Tinned Copper Oxygen-Free Insulated Red& Black Electrical Cable for Boat/Automotive/RV/Camper/Trailer --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/20918658-blue-sea-systems-7189-285-series-thermal-circuit-breakers-surface](https://www.desertcart.no/products/20918658-blue-sea-systems-7189-285-series-thermal-circuit-breakers-surface) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-17*
