Rated 693 A at 690 V, with an integrated NTC thermistor for module temperature monitoring — this NTC signal feeds back to the soft starter control board for over-temperature protection and current foldback logic. Fits the power section of the 3RW44 series soft starters — a field-replaceable assembly that carries the main motor current during start and bypass. The NTC output is a critical input to the starter's thermal model. ## Compliance and documentation Siemens provides standard compliance documentation including CE declaration, RoHS and REACH statements, and UL recognition for the 3RW44 series — these are available on request with the RFQ. ## Ordering and supply posture Submit an RFQ for current pricing, lead time, and lot traceability. Availability is confirmed per inquiry — no stock-holding claim is made here.","metaTitle":"Siemens 3RW4755-0NC00 Power Semiconductor Module, 693 A","metaDescription":"Siemens 3RW4755-0NC00 power semiconductor module, 693 A, 690 V, for 3RW4453/4454/4455 soft starters.
