Panel fit and wiring constraints
The 3RT2015-1AV61 measures 45 mm wide, 58 mm high, and 73 mm deep — the depth is the dimension to check when retrofitting into a shallow enclosure or one with a backplane already populated with busbars or terminal blocks.
Duty-cycle limits for motor switching
The S00 frame is Siemens' smallest contactor footprint, typically covering motor loads up to about 7 kW in AC-3 duty — the exact rating depends on the coil voltage variant and ambient temperature. Switching frequency is duty-dependent: 1000 operations per hour in AC-1 (resistive), 750 ops/h in AC-3 and AC-2 (motor starting and reversing), and 250 ops/h in AC-4 (plugging/inching) — the AC-4 ceiling is the one to respect for jogging or reversing applications to avoid overheating the contacts.
The lifecycle stage is listed as 'current' — Siemens still produces this part under the SIRIUS brand, so it is not a legacy or phase-out item. The auxiliary switch is included as standard, which simplifies BOM consolidation — no separate aux block to order for basic signalling.
