The Powerex 12-810096-00-R2, corresponding to manufacturer module type ND431625NI, is a heavy-duty 1600 V, 250 A dual phase-control thyristor module from the Powerex POW-R-BLOK family. It combines two high-current SCRs in a single electrically isolated power block for industrial AC power control, rectification, soft-starting, and critical-power applications.
The module is rated for approximately 393 A RMS on-state current and provides substantial non-repetitive surge capability, including up to approximately 8.8 kA for a single 60 Hz cycle. This makes the module particularly suitable for equipment exposed to high inrush currents, line transients, and demanding industrial duty cycles.
Its isolated baseplate and compression-bonded power elements provide efficient heat transfer while maintaining electrical isolation from the heatsink and chassis. Heavy-duty M8 power terminals handle the primary current path, while dedicated control connections provide reliable triggering of the internal thyristors.
The 12-810096-00-R2 number may appear as an equipment-specific or customer part number, while ND431625NI identifies the underlying Powerex semiconductor module. For legacy UPS and industrial power equipment, both numbers should be checked when identifying a replacement.
