Why Choose the Mersen P300117 Protistor® High-Speed Fuse?
The Mersen P300117 is a Protistor® Size 30 aR high-speed square body fuse designed to provide maximum protection for semiconductor devices used in modern power conversion equipment. Manufactured by Mersen, this fuse features a 400A current rating, 690VAC IEC / 700VAC UL voltage rating and DIN 80 blade terminals with an integrated striker, making it ideal for demanding industrial applications.
Engineered specifically for the protection of diodes, thyristors, IGBTs and MOSFETs, the P300117 combines low let-through energy (I²t), high interrupting capacity and ultra-fast fault clearing to minimise damage during short-circuit conditions. It is widely used in variable speed drives, UPS systems, industrial inverters, converters and other power electronic equipment.
Protistor® semiconductor fuses are manufactured using die-cut silver elements embedded in solidified silica sand, providing controlled arc extinction, excellent reliability and consistent performance under demanding industrial operating conditions. Silver-plated contact surfaces and non-magnetic hardware further enhance long-term reliability.
