EGIS Thermal Circuit Breakers: Built for Reliable Marine Power
Published on
January 30th, 2026
At MurCal, we’re proud to highlight EGIS Mobile Electric as our Brand of the Month. Their thermal circuit breakers are built for reliability and tough marine conditions. Made with precision American engineering and backed by a 4-year warranty, these breakers protect your boat’s electrical system with proven quality.
Smart Protection Made Simple
EGIS thermal circuit breakers automatically guard against short circuits and overloads. They also work as handy on/off switches. Each unit meets IP67 standards, making it resistant to water, dust, and corrosion. They function smoothly in temperatures from -25°F to 180°F, with voltage ratings up to 72VDC and interrupt capacity up to 5,000A at 14VDC. Available in models from 25A to 250A, they handle tough marine power demands with ease.
High-visibility yellow controls, stainless steel hardware, and built-in terminal insulators make them safe, durable, and easy to use.
Made for Serious Boaters and Professionals
These breakers are trusted by commercial fishermen, offshore racers, and yacht owners who can’t risk electrical failures. Recreational boaters updating their systems will also appreciate their reliability in saltwater conditions. Whether you’re wiring a new vessel or upgrading an older one, EGIS delivers professional-grade performance for any marine setup.
Reliable in Harsh Conditions
Install these breakers where the environment is toughest—engine rooms, open decks, or battery bays. Their compact design fits tight spaces, while durable materials resist high heat, vibration, and fuel vapor exposure. No matter where you mount them, they’re built to last.
Confidence When It Matters
EGIS breakers protect vital equipment like trolling motors, winches, and inverter systems. They trip instantly during faults, preventing wire damage or fire risk. Then, a quick lever reset gets you running again—no fuses to hunt for. In rough conditions or heavy-load situations, these breakers are essential protection for your crew and your boat.
