Panel fit and mounting constraints
The 3RT2035-1AF00: These spacings govern gland-plate fill factor and adjacent device placement in a crowded enclosure.
Switching capacity and duty-cycle planning
Rated 40 A at 480 V in AC-3 duty — this is the motor-switching current that drives the contactor selection for a 40 A full-load-amp motor branch. The AC-3 rating governs the make/break of squirrel-cage motors during running starts; the AC-4 rating of 300 operations per hour limits plugging and inching duty cycles. Mechanical switching rates: 1,200 ops/h in AC-1 (resistive), 1,000 ops/h in AC-3, and 300 ops/h in AC-4. The arcing time of 10–20 ms and closing time of 10–18 ms set the minimum off-time between cycles — relevant for high-speed reversing or jogging applications.
Auxiliary contact count and coil termination
The contactor carries an auxiliary switch block configurable from 1 NO to 8 NO + 1 NC (18...1 range). This covers feedback to a PLC input for status monitoring or interlocking without an add-on block in many cases. Coil ratings at 50 Hz include 110 V and 230 V (, 7.5 hp) — confirm the control voltage matches the panel's control transformer tap.
Environmental envelope and storage limits
The 10 million typical mechanical life assumes clean, dry conditions within these limits — derate the electrical life for high-humidity or corrosive atmospheres.
