Panel fit and DIN-rail mounting
The 3RT2035-1AP04 is a SIRIUS power contactor, size S2, with a 55 mm width that occupies three standard 18 mm DIN-rail modules. Depth is 174 mm, height 114 mm — the footprint fits alongside other SIRIUS components in a common panel layout.
Switching endurance across duty classes
Rated for 1,200 operations per hour in AC-1 (resistive load), 750/h in AC-2 (slip-ring motors), 1,000/h in AC-3 (squirrel-cage motors), and 300/h in AC-4 (plugging/inching). The AC-3e rating matches the standard AC-3 at 1,000 ops/h — this is the figure most panel builders use for motor starting duty. The arcing time spans 10–20 ms, with switching times of 10–18 ms — these numbers matter when coordinating contactor opening with upstream breaker trip curves in a selective coordination study.
Coil voltage and terminal details
The coil is rated for 230 V at 50 Hz, 7.5 hp at 230 V — this is the standard North American motor horsepower rating at that voltage. No auxiliary switch is integrated; an external auxiliary contact block is needed for status feedback.
Thermal envelope and storage limits
The 60 °C ceiling is typical for enclosed panels without forced ventilation — above that, derate the continuous current per the SIRIUS application manual.
