When it comes to safeguarding industrial electrical systems, the Bussmann 170M6464 fuse stands out as a reliable solution. Designed for high-voltage applications, this 690VAC/500VDC fuse delivers exceptional short-circuit protection with a breaking capacity of 200kA. Its compact design and DIN-style mounting make it ideal for tight spaces in motor control centers (MCCs) and power distribution panels.A recent case study from a German automotive plant demonstrates its value: After replacing older fuses with the 170M6464 series, the facility reduced equipment downtime by 32% over 18 months. The fuse’s silver-sand construction ensures stable performance even in temperature fluctuations (-50°C to +125°C), critical for foundries and outdoor renewable energy installations.Industry data shows a growing adoption rate – 45% of new European industrial projects now specify the 170M6464 for motor protection circuits. Its time-delay characteristic (10s at 500% rating) prevents nuisance tripping during motor startups while maintaining fast response to actual faults. For maintenance teams, the visible striker pin provides clear fault indication, cutting troubleshooting time by an average of 28 minutes per incident.
