Mersen PC92UF15C200TF Protistor High-Speed Fuse, 200A 1500VAC, Size 92 aR, Square Body Flush End with Striker (F076158)

Mersen Protistor® High-Speed Semiconductor Protection Fuse | 200A 1500VAC

The Mersen PC92UF15C200TF (Part Number: F076158) is a high-performance square body fuse-link within the Protistor® PSC series, specifically engineered for the ultra-fast protection of power semiconductor devices. This Size 92 fuse is designed for 1500VAC applications with a 200A rating, providing maximum security for today’s power conversion equipment including SCRs, diodes, thyristors, GTOs, and IGBT devices.

Developed under the URF design specification, this fuse-link features pure silver die-cut elements embedded in solidified sand, which provides precise control over arcing characteristics. This results in extremely low I²t clearing values and a high breaking capacity of 200kA. The construction includes silver-plated contact surfaces and non-magnetic hardware to ensure high conductivity and durability. Each unit is equipped with a low-voltage trip-indicator (striker), which can be used to operate a field-mountable microswitch for remote status monitoring, even while the system is in service.

Key Features:

• Extremely Fast Acting: aR characteristic provides high-speed response to protect sensitive power electronics from overcurrent.
• High Interrupting Rating: Rated for 200kA at 1500VAC, suitable for high-energy industrial applications.
• Low Energy Let-Through: Engineered for very low I²t to minimize fault-related damage to downstream components.
• Remote Signaling Ready: Includes a mechanical striker for immediate visual indication and microswitch compatibility.
• Robust Construction: Ceramic body with silver-plated flush end contacts for secure, low-resistance mounting.
