Mersen PC292UG15C500TF Protistor High-Speed Fuse, 500A 1500VAC, Size 2x92 aR, Square Body Flush End with Striker (P075844)

Mersen Protistor® High-Speed Semiconductor Protection Fuse | 500A 1500VAC

The Mersen PC292UG15C500TF (Reference Number: P075844) is an ultra-fast-acting fuse from the Protistor® PSC Square Body series, specifically engineered for the high-demand protection of power semiconductors. This Size 2x92 dual-body fuse is designed for heavy industrial applications requiring a rated current of 500A and a high-voltage capacity of 1500VAC. It provides a highly reliable safety solution for power rectifiers, UPS systems, variable speed drives, and other high-power conversion equipment.

Classified under the "aR" utilization category, this fuse offers superior short-circuit protection with extremely low I²t let-through values, ensuring that sensitive electronic components like diodes, thyristors, and IGBTs are shielded from catastrophic failure. The Square Body Flush End configuration (Type C) allows for a low-inductance connection via metric internal threads, which is vital for high-frequency power electronics. This model is equipped with a mechanical Type TF striker for local trip indication and is compatible with microswitches for remote fault detection.

Key Features:

• High-Speed Semiconductor Grade: Optimized aR characteristic for the rapid clearance of faults in power electronic circuits.
• High Voltage Rating: Specifically designed to operate safely in 1500VAC systems, common in heavy industrial and traction power.
• Dual Body Design (Size 2x92): Provides high current density and excellent thermal performance within a specialized footprint.
• Superior Breaking Capacity: Rated to interrupt fault currents up to 150kA at 1500VAC, ensuring maximum system protection.
• Low Power Loss: Engineered with silver-plated copper contacts to minimize resistance and reduce heat generation during continuous operation.
• Integrated Monitoring: Features a high-reliability TF striker for instant visual trip status and remote signaling integration.
