Mersen N076464 MI6FA100V0.4 very fast-acting semiconductor miniature fuse rated at 0.4 A and 1000 V AC, with a 6.3 × 46 mm format and 30 kA minimum breaking capacity.
£7.80
The Mersen N076464 is a compact, very fast-acting semiconductor miniature fuse designed to protect sensitive electronic components against damaging overcurrents and short-circuit faults. Part of the Mersen MI6FA100V0.4 range, it combines a high voltage rating with rapid fault interruption for dependable protection in demanding electronic and industrial equipment.
Its FA high speed operating characteristic enables the fuse to disconnect a fault before excessive energy can damage vulnerable semiconductor devices. This makes it particularly suitable for power electronics, industrial control equipment, instrumentation and other circuits where conventional general-purpose fuses may not operate quickly enough.
With a rated current of 0.4 A, a rated voltage of 1,000 V AC and a minimum breaking capacity of 30 kA, the N076464 provides reliable protection in a compact 6.3 × 46 mm clip-mounted format. Its ceramic body and low-energy operating characteristics support dependable performance in sensitive electronic applications.
High speed semiconductor fuses are engineered to limit the electrical energy passed during a fault, helping prevent permanent damage to delicate semiconductor components. Their rapid operating characteristics are especially important in circuits where even a brief overcurrent could cause costly equipment failure.
The Mersen N076464 combines a 1,000 V rating, low I²t values and a high breaking capacity, making it well suited to electronic and industrial systems where fast fault clearance, compact dimensions and dependable circuit protection are essential.
