Why Choose the Mersen Z084363 Miniature Semiconductor Fuse?
The Mersen Z084363 is a compact 6.3 × 32 mm high-speed semiconductor fuse designed to provide rapid protection for sensitive electronic components and power-semiconductor devices. Also identified by catalogue number MI6FA40V6.3, it has a rated current of 6.3 A and a rated voltage of 400 V AC.
Part of the Mersen FA/FB miniature semiconductor fuse series, the Z084363 features a very fast-acting FA characteristic. This allows it to interrupt excessive current quickly, helping minimise the thermal and electrical energy transferred to diodes, thyristors, rectifiers, converters and other sensitive semiconductor components.
The fuse is manufactured with a durable ceramic insulating body and ferrule terminals for installation in compatible clip-mounted fuse holders. Its compact cartridge design, 150 kA minimum interrupting rating and low let-through energy make it suitable for industrial automation, power electronics, instrumentation and OEM equipment.
