Each device requires two of these modules to handle the full 693 A rating at 690 V. Rated 693 A, this module carries the main motor current during the start and bypass phases. The 690 V voltage class covers 400 V and 690 V line supplies common in European and industrial installations. ## Lifecycle and compliance — active, RoHS-compliant As a Siemens-branded module, it carries full OEM traceability. ## Integration into the 3RW44 soft starter system Two 3RW4755-0LC00 modules mount inside the soft starter enclosure, one per phase pair, to form the thyristor stack. The 693 A rating per module means the combined assembly handles the full motor start current without external bypass contactors in most applications. The module is designed for the 3RW44 series — confirm the host soft starter model (3RW4453, 3RW4454, or 3RW4455) before ordering. The 690 V rating covers both 400 V and 690 V line voltages, so the same module serves both common supply levels.","metaTitle":"Siemens 3RW4755-0LC00 Power Semiconductor Module, 693 A","metaDescription":"Siemens 3RW4755-0LC00 power semiconductor module, 693 A, for 3RW4453/4454/4455 soft starters.
