High-speed semiconductor protection fuse with double indicator and plain blades, rated 100A, 690VAC IEC / 700VAC UL, NH size 00.
£46.18
The Mersen NH00UD69V100PV is a Protistor® NH Size 00 high-speed semiconductor fuse developed to protect sensitive power electronic equipment against damaging short-circuit currents. Its ultra-rapid aR operating characteristic provides fast current limitation for semiconductor devices such as diodes, thyristors, rectifiers and IGBTs.
Designed for demanding industrial environments, the NH00UD69V100PV uses a robust ceramic square body with high-performance fuse elements and NH blade contacts. This construction helps reduce peak fault current and let-through energy, protecting valuable electronic components and limiting disruption to drives, converters, inverters and power supplies.
Rated at 100 A and 690 V AC, this NH Size 00 fuse is suitable for installation in compatible NH fuse bases and fuse switch disconnectors. Its double visual indicator allows engineers to identify an operated fuse quickly during inspection and maintenance.
Semiconductor devices can be permanently damaged by excessive fault energy in a very short period. The Mersen NH00UD69V100PV is engineered to operate rapidly during serious short-circuit conditions, reducing the peak current and thermal energy transferred to connected electronic components.
Because it has an aR utilisation category, the fuse is primarily intended for semiconductor short-circuit protection. Suitable overload protection may also be required, depending on the equipment design, operating conditions and recommendations of the system manufacturer.
