Product details

SIRIUS reversing starter — panel-ready dimensions and protection

The 3RK4353-3CR58-1BA0 is a Siemens SIRIUS reversing motor starter with MCU-controlled on-site assignment, meaning it handles forward/reverse switching in a single package without external contactor interlocking.

Mounting and supply voltage — what fits

Dimensions are 145 mm deep, 182 mm wide, 220 mm tall — measure the backpanel real estate before committing; the reversing contactor pair takes up more width than a single-direction starter.

Lifecycle and sourcing — current production, quoted per BOM

Sourced through independent distribution channels; availability and volume pricing confirmed at RFQ against your BOM quantity. RoHS compliance date is 05/01/2012 — the unit meets the substance restrictions effective from that date.
