Mersen PC292UK15C630TF Protistor High-Speed Fuse, 630A 1500VAC, Size 2x92 aR, Square Body Flush End with Striker (S076241)

Mersen Protistor® High-Speed Semiconductor Protection Fuse | 630A 1500VAC

The Mersen PC292UK15C630TF (Reference Number: S076241) is an ultra-fast-acting semiconductor protection fuse part of the high-performance Protistor® PSC Square Body series. Engineered for the specialized protection of high-power semiconductor devices, this Size 2x92 dual-body fuse is designed to operate at 630A with a rated voltage of 1500VAC. It is a critical component for safeguarding large-scale power electronics such as industrial rectifiers, AC/DC drives, and traction power substations.

Consistent with the "aR" utilization category, this fuse provides partial-range short-circuit protection, characterized by extremely low I²t let-through values and high-energy clearing capabilities. The Square Body Flush End (Type C) design features internal metric threads, ensuring a low-inductance connection and optimal thermal transfer to busbars. It includes a built-in mechanical Type TF striker, which serves as a trip indicator and can be used to trigger remote microswitches for real-time fault monitoring in industrial control systems.

Key Features:

• Precision Semiconductor Defense: Optimized aR curves for the protection of diodes, SCRs, thyristors, and IGBT modules.
• High-Voltage Stability: Rated for 1500VAC, providing reliable performance in advanced industrial and utility-grade power networks.
• Size 2x92 Dual Body: Enhanced current-carrying capacity and thermal dissipation through an optimized square-body geometry.
• Extremely High Breaking Capacity: Capable of safely interrupting fault currents up to 150kA, preventing extensive equipment damage.
• Efficient Operation: Low power dissipation and minimized resistance via silver-plated copper contact surfaces.
• Fault Indication: Integrated TF striker provides instantaneous local trip status and facilitates remote signaling.
