Before selecting an alternative, confirm its dimensions, terminals and installation requirements in the manufacturer documentation.
The 6EP1333-220 is the device-level element in a Siemens circuit breaker installation. It receives the field signals and control supply listed above — <= 440 V AC — and switches or conditions the load within the <= 440 V AC ratings shown in the Specifications table. Wiring and protective devices are sized to those same numbers, not to a generic assumption.
Typical installations place it in distribution boards, motor protection circuits, panel feeders, where the unit is matched to the original catalog number and the enclosure provides 35 mm DIN rail (IEC 60715) support. Record the catalog number and revision from the nameplate of the installed unit before specifying a like-for-like spare.
Siemens 6EP1333-220 — Industrial automation component supplied as a like-for-like replacement, selected by catalog number and published ratings. The figures below are taken from the specification table on this page for catalog number 6EP1333-220; size the surrounding wiring and upstream protection to these published ratings rather than to a generic assumption.
Datasheets and compliance documents are available on request; quote the full catalog number when enquiring.
