432 A, 600 V — replacement module for 3RW4076
The Siemens 3RW4776-0LB00 is a power semiconductor module rated 600 V and 432 A, designed as the internal switching assembly for the 3RW4076 soft starter series. At 432 A, this module handles the full motor current during start and run — the soft starter's thyristor stack is what limits inrush, not the module itself.
