Same-class peers worth a look
The ABB B7-30-10-80 sits in the same contactor family on the catalog page and is the closest peer carried in evidence for cross-shopping the 1SBL181001R8510, but it is a different order code with its own coil and contact configuration — treat it as a same-line alternate to evaluate, not as a confirmed drop-in swap without checking the coil voltage and aux block against your drawing.
