Mersen PC293UG15C750TF Protistor High-Speed Fuse, 750A 1500VAC, Size 2x93 aR, Square Body Flush End with Striker (Y076246)

Mersen Protistor® High-Speed Semiconductor Protection Fuse | 750A 1500VAC

The Mersen PC293UG15C750TF (Reference Number: Y076246) is a high-performance, ultra-fast-acting fuse from the renowned Protistor® PSC Square Body series. This Size 2x93 dual-body fuse is engineered to provide superior protection for semiconductor devices, offering a rated current of 750A and a high voltage capacity of 1500VAC. It is designed for demanding industrial power electronics applications, including massive power converters, UPS systems, motor drives, and chemical electrolysis equipment.

Classified under the "aR" utilization category, this fuse provides specialized partial-range short-circuit protection for components such as diodes, thyristors, and IGBTs. It is optimized for extremely low I²t let-through values and fast clearing times to minimize fault energy and prevent damage to delicate semiconductor junctions. The Type C Flush End mounting features internal metric threads for a secure, low-resistance connection to busbars. Additionally, the integrated Type TF mechanical striker provides localized trip indication and allows for the mounting of microswitches to facilitate remote fault monitoring and system interlocking.

Key Features:

• Ultra-Fast Acting: Specialized aR curve designed to protect power semiconductors by limiting peak fault currents.
• High Voltage Rating: Rated for 1500VAC, suitable for high-power distribution and conversion networks.
• Dual-Body Size 2x93: Optimized geometry for high current carrying capacity and efficient thermal management.
• Superior Breaking Capacity: Capable of safely interrupting fault currents up to 150kA at 1500VAC.
• Reliable Connection: Flush-end metric threaded design ensures a compact footprint and low-inductance installation.
• Fault Monitoring: Built-in TF striker offers immediate visual status and supports automated system alerts through microswitch integration.
