It mounts as a retrofit on 3RW44 frames 3RW4453, 3RW4454, and 3RW4455. This keeps the motor at line voltage during run, dropping the thermal load on the soft starter and extending its duty cycle for heavy-start applications like crushers or conveyors.","metaTitle":"Siemens 3RW4755-0KC00 Bypass Unit, 3RW44 Kit, Current","metaDescription":"Siemens 3RW4755-0KC00 bypass unit for 3RW4453-3RW4455 soft starters.
