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

Frequently Asked Questions

1. What is the Eaton Bussmann Series High Speed Square Body Fuse 170M1563D designed for, and what makes it “high-speed”?
2. This fuse is specifically designed for high-speed applications in critical electrical systems, providing rapid protection against short circuits. The “high-speed” characteristic refers to its low pre-arcing I²T value (65), which indicates the minimal amount of energy required to clear a fault. This allows for very quick fault interruption, minimizing damage to connected equipment and improving overall system safety.
3. What are the key electrical specifications of the 170M1563D fuse, such as amperage, voltage, and breaking capacity?
4. The 170M1563D fuse has a 40A amperage rating, a voltage rating of AC 690V (IEC) and 700V (UL), and a breaking capacity of 200kA. It’s designed with a gR class, indicating superior short-circuit protection, and also has a clearing I²T value of 490 at 660V. These specifications highlight its ability to handle significant fault currents and provide robust protection in demanding environments.
5. What does “gR class” mean in the context of this fuse, and why is it important?
6. The “gR class” refers to the fuse’s performance category as a high-speed fuse designed for semiconductor protection. gR fuses provide exceptionally fast response times and current limiting capabilities, which are crucial for protecting sensitive electronic components from damaging short-circuit currents. They are more protective than general-purpose fuses, ensuring the safe and reliable operation of power electronics.
7. What do the I²T values, specifically ‘pre-arc I²T’ and ‘clearing I²T’, represent for this fuse?
8. The pre-arc I²T (65) represents the amount of energy required for the fuse element to melt before an arc is established. The clearing I²T (490 at 660V) represents the total energy dissipated within the fuse during the fault-clearing process until the arc is extinguished. Both values are critical indicators of the fuse’s speed and energy-limiting capability during a fault condition. Lower pre-arc values mean faster response times, while the clearing I²T indicates the total stress a fuse experiences during fault clearance.
9. What certifications and compliances does the 170M1563D fuse have, and why are these important for users?
10. The 170M1563D fuse is CE marked, RoHS compliant, and is UL 512 certified as well as UL recognized and IEC rated. These certifications and compliances ensure the product meets international safety and environmental standards. The CE mark indicates conformity with European safety standards, RoHS compliance restricts the use of hazardous materials, and UL certification ensures safety and performance standards have been independently verified. These certifications provide confidence to users that the fuse is safe, reliable, and compliant with relevant regulations.
11. How is the 170M1563D fuse designed for ease of use and safety?
12. The fuse is designed with a DIN 000 standard and includes dual indicators to show if the fuse has blown. It also incorporates live gripping lugs to ensure safe and easy handling. This design allows for quick and convenient installation and replacement while minimizing the risk of electrical shock during maintenance.
13. Where can the 170M1563D fuse be purchased, and what are the benefits of buying from Shansen Enterprises?
14. The 170M1563D fuse can be purchased from Shansen Enterprises, an authorized channel partner for Eaton Bussmann products.
