It is rated for 5.5-8 A and uses a 24 VAC control voltage. The MSP has no auxiliary contacts fitted; the contactor carries one normally open auxiliary contact. The 5.5-8 A current range sets the thermal overload setting window. For a motor with a full-load current in that band, the integrated MSP provides short-circuit and overload protection without a separate motor circuit breaker. The 24 VAC control coil is standard for panels where a control transformer supplies the AC safety voltage. Because the starter is nonreversing, it handles one direction of rotation only — if your application needs forward/reverse, this unit is not the fit. The S00 frame size determines the physical envelope: it occupies a single-width slot on the Fastbus rail, which governs how many devices fit in a given panel width. The lifecycle stage for this order code is listed as current, meaning Siemens has not flagged it for discontinuation or last-time buy. It remains an active catalog item within the SIRIUS family. No official successor order code has been published because the part is still in the active portfolio.","metaTitle":"Siemens 3RA1110-1HA16-1BW4 Combination Starter, S00, 5.5-8A","metaDescription":"Siemens 3RA1110-1HA16-1BW4 nonreversing combination starter, SIRIUS S00 frame, 5.5-8 A, 24 VAC control.

For reversing duty you would need a different order code from the SIRIUS family."},{"question":"What is the frame size of Siemens 3RA1110-1HA16-1BW4?","answer":"Frame size S00, which is the smallest SIRIUS frame. It determines the physical width on the Fastbus mounting rail and the maximum current the device can handle."},{"question":"Where can I buy the 3RA1110-1HA16-1BW4 combination starter?","answer":"This order code is sourced to order against an RFQ through independent distribution channels.
