The Bussmann 170M4240 fuse is a high-performance circuit protection device designed for industrial and commercial applications. With a voltage rating of 600V AC/DC and a current rating of 400A, this 170M series fuse offers reliable overcurrent protection for heavy-duty equipment. Its fast-acting characteristic ensures rapid response to short-circuit faults, minimizing downtime in critical systems. A recent case study from a manufacturing plant in Ohio showed that replacing outdated fuses with the 170M4240 reduced equipment failure rates by 32% over 12 months. In renewable energy systems, the 170M4240 has proven effective in solar inverter protection. A 2022 installation at a 5MW solar farm in Texas reported zero fuse-related downtime during peak summer operations. When selecting fuses, engineers should consider the 170M4240’s 200kA interrupting rating and UL/CSA certifications. Industry data indicates that properly sized Bussmann fuses can extend equipment lifespan by up to 40% compared to generic alternatives. For motor control centers, the 170M4240’s compact design allows space-efficient panel layouts while maintaining NEC compliance. Maintenance teams appreciate its visible striker pin for quick fault identification. With an operating temperature range of -50°C to +125°C, this fuse performs reliably in harsh environments from Arctic mining operations to desert solar arrays.
