The Bussmann 200LMT fuse has become a go-to solution for engineers seeking reliable overcurrent protection in high-voltage systems. As part of Eaton’s Bussmann series, this 200LMT model combines UL-recognized performance with rugged durability, rated for up to 200kV applications. Let’s explore how this fuse delivers value across industries through real-world scenarios. In renewable energy systems, solar farm operators report 60% fewer transformer failures after implementing 200LMT fuses in their 150kV DC combiner boxes. The fuse’s fast-acting design (clearing faults within 1/4 cycle) prevents cascading damage in photovoltaic arrays. A wind turbine manufacturer in Germany documented a 42% reduction in maintenance costs after standardizing on 200LMT units for their 33kV collector circuits. For industrial motor protection, a steel mill in Ohio credits these fuses with preventing $2.3M in downtime costs during voltage surge events. The 200LMT’s silver-sand construction ensures stable performance across temperatures from -40°C to 90°C, crucial for foundry environments. Data center operators particularly appreciate its 200kA interrupting rating – essential for safeguarding 480V UPS systems against catastrophic faults. Recent UL testing shows the 200LMT maintains consistent trip characteristics even after 10,000+ operational cycles. While competitors like Littelfuse offer similar specs, field data from 50+ industrial plants indicates Bussmann’s design achieves 15% faster fault clearing in 480V applications. Engineers should note the fuse’s compact 200A rating makes it ideal for retrofit projects where space is constrained. For optimal performance, pair with Eaton’s CPS-2 fuse holders in corrosive environments.
