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.
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.
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.
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.
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.
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.
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.
