Conflicting Data Resolution
Note: Discrepancies in evidence require clarification:
- Incorrect PLC/Contactor Claims: misattribute specifications (e.g., 24V I/O, IP55 rating) to this IGCT module. These describe unrelated ABB PLCs.
- Voltage/Current Variances:
- (220V/45A) and (400V/45A) refer to ABB circuit breakers (e.g., S-series breakers), not this IGCT.
- Excitation Control Reference: describes a computing module (Intel Ivy Bridge, DDR3 RAM) – likely a system using the IGCT, not the device itself.
