Eaton Bussmann 400MMT Fuse Link: High-Speed Protection FAQ
The primary purpose of this fuse link is to provide reliable and high-speed protection for electrical circuits, particularly in semiconductor applications and other high-power environments. Its Class aR characteristics make it suitable for protecting sensitive components from overcurrent and short-circuit events.
This fuse link is rated for 690 VAC and 350 VDC according to IEC standards, and 700 VAC according to UL standards. It has a current rating of 400A, allowing it to handle substantial power loads.
The 400MMT Eaton Bussmann fuse has a breaking capacity of 200 kA RMS Sym. (IEC/UL) and 40 kA DC at 350 VDC (IEC). This high breaking capacity indicates its ability to safely interrupt very high short-circuit currents, preventing damage to equipment and ensuring safety.
“Class aR” signifies that this fuse is specifically designed for semiconductor protection. It provides extremely fast-acting protection to prevent damage to sensitive semiconductor devices during overcurrent conditions. The “aR” designation indicates that the fuse offers partial range protection, meaning it’s designed to interrupt high fault currents but may not protect against low overloads.
This fuse link is suitable for semiconductor protection, DC common bus systems, DC drives, and power converters/rectifiers, among other applications requiring reliable and rapid overcurrent protection.
The 400MMT Eaton Bussmann fuse is certified for both IEC and UL standards, CE Marked, RoHS Compliant, and designed and tested to BS88 part 4 and IEC 60269-4. These certifications ensure it meets global safety and performance requirements.
The double barrel design enhances thermal efficiency and increases the current carrying capacity of the fuse. This design helps dissipate heat more effectively, allowing the fuse to operate reliably under high-current conditions.
