FAQ:Eaton Bussmann Series High Speed Square Body Fuse 170M1563D

Why this FAQ?
This FAQ brings together the most common questions about the Eaton Bussmann 170M1563D high-speed fuse—covering its design, ratings, certifications, and safe use. It’s meant to give engineers, buyers, and maintenance teams quick clarity without digging through datasheets.

[faq question=”What is the Eaton Bussmann Series High Speed Square Body Fuse 170M1563D designed for, and what makes it high-speed?”]
This fuse is designed for high-speed protection of critical electrical systems. Its “high-speed” behavior comes from a low pre-arc I²T of 65, enabling rapid short-circuit interruption to minimize equipment damage and improve system safety.
[/faq]

[faq question=”What are the key electrical specifications of the 170M1563D fuse?”]
40 A current rating; voltage: 690 V AC (IEC) / 700 V (UL); breaking capacity: 200 kA; class: gR; clearing I²T: 490 at 660 V. Built for robust short-circuit protection in demanding environments.
[/faq]

[faq question=”What does gR class mean for this fuse?”]
gR denotes a high-speed fuse optimized for semiconductor protection, with extremely fast response and strong current-limiting action—more protective than general-purpose fuses for sensitive power electronics.
[/faq]

[faq question=”What do the pre-arc I²T and clearing I²T values indicate?”]
Pre-arc I²T (65) is the energy needed for the element to melt before an arc forms—lower values mean faster response. Clearing I²T (490 at 660 V) is the total energy through the fuse until the arc extinguishes, indicating overall stress during fault clearing.
[/faq]

[faq question=”What certifications and compliances does the 170M1563D have?”]
CE marked, RoHS compliant, UL 512 certified/recognized, and IEC rated—assuring conformity to international safety and environmental standards for reliable, compliant use.
[/faq]

[faq question=”How is the 170M1563D designed for ease and safety?”]
DIN 000 form factor, dual blown-fuse indicators, and live gripping lugs for safer handling—making installation and replacement quick and maintenance-friendly.
[/faq]

[faq question=”Where can I buy the 170M1563D, and why Shansen Enterprises?”]
