SIEMENS 3ZX1012-0RT02-1AA1 Accessory Module

The Siemens 3ZX1012-0RT02-1AA1 is an SIRIUS series accessory / ordering reference module used in Siemens motor control and contactor systems. It is typically associated with SIRIUS contactor assemblies (3RT series) and related motor starter components such as auxiliary contacts, overload relay combinations, or configuration/accessory kits.

This code is not a standalone functional device like a PLC or relay, but rather a system accessory / order-related module reference used for assembling or completing SIRIUS switching devices.
