Siemens / ITE CF3B100 – 100A 3 Pole Molded Case Circuit Breaker Genuine

Built for heavy-duty industrial environments, this 100A current-limiting MCCB safeguards critical electrical circuits against severe faults. The bolt-on configuration mounts into classic Siemens switchboards, providing a seamless match without requiring modern adapters. Now superseded by the CED63B100, this original CF-frame breaker achieves a massive 200kAIC interrupting capacity at 480V by utilizing integral Amp-Trap fuses to restrict let-through energy.
