For a 22 kW slip-ring motor on 400 V three-phase, this contactor lands on the critical path; anything smaller and you're derating into the next outage window. ## DIN Rail Fit and Terminal Reality Side-by-side mounting is permitted, so zero gap between contactors on the rail, but watch the heat buildup at AC-3 max 800 switching cycles per hour. ## Terminal Capacity and Wire Prep Solid wire: 2x (0.25 to 2.5 mm²). Stranded: 2x (0.75 to 25 mm²). The combined solid-or-stranded range is 2x (0.75 to 16 mm²) — that's the practical working range for panel builders. Strip and torque per the terminal marking; the 25 mm² stranded upper end is for the main power feed, not the control loop. ## Environmental and Protection Class Front face rated IP20; the terminal area is IP00 — that's typical for a panel-mounted contactor where the enclosure provides the overall seal. ## Switching Performance and Mechanical Life Mechanical life is typical 10,000,000 operations. At 50 Hz the operating range is 0.8 to 1.1 times rated voltage; at 60 Hz it's 0.85 to 1.1. The auxiliary contact ratings at 24 V are 10 A, at 60 V 2 A, at 110 V 1 A, at 220 V 0.3 A — these govern the control circuit load, not the main power path. ## Switching Frequency by Duty Class Maximum switching frequency varies by duty: AC-1 (resistive) at 1000 cycles/hour, AC-2 (slip-ring motor) at 400 cycles/hour, AC-3 (squirrel-cage motor) at 800 cycles/hour, AC-4 (plugging/inching) at 300 cycles/hour. For a conveyor drive cycling at 600 per hour, the AC-3 rating clears it; for a crane hoist with reversing starts, the AC-4 ceiling of 300 is the hard limit.","metaTitle":"Siemens 3RT1036-3AL20-ZX95 SIRIUS Power Contactor, S2, 22 kW","metaDescription":"Siemens SIRIUS power contactor 3RT1036-3AL20-ZX95, size S2, rated 22 kW at 400 V AC-2.
