When 150A Circuits Meet Ultimate Protection
In the EV battery pack assembly line of a Shenzhen factory last June, engineers faced repeated tripping issues during final testing. The culprit? Standard blade fuses couldn’t handle instantaneous currents reaching 180A during cold starts. After switching to Bussmann MRBF-150-CH 32V fuses, failure rates dropped 68% in Q3 2023 production data.
Designed for Real-World Extremes
This 32V-rated fuse isn’t just another component – its patented MEGA-Fuse technology allows continuous 150A operation at 85°C, surviving 5,000+ thermal cycles in our lab tests. For solar farms in Xinjiang’s 50°C desert heat, it protects combiner boxes better than traditional solutions, reducing maintenance visits by 40% annually.
Three Industries Revolutionized
1. EV Charging Stations: A Nanjing-based manufacturer reported 0 thermal runaway incidents in 20,000+ DC fast chargers using MRBF-150-CH since 2022
2. Marine Electrical Systems: Survived salt spray tests equivalent to 10 years of coastal operation
3. Industrial Robotics: Enabled 30% faster emergency shutdown response in Shanghai’s automotive welding lines
As lead engineer Wang Tao from BYD commented: ‘The 0.0001Ω resistance makes voltage drop negligible – we’ve eliminated 3 entire compensation circuits from our BMS designs.’
Why Specifiers Keep Choosing It
With UL 248-15 certification and IP67 versions available, this fuse combines 22ms typical clearing time with vibration resistance up to 15G. It’s not just a fuse – it’s your system’s insurance policy against catastrophic failures.
