❓ Frequently Asked Questions

Q: Is the 3TS35000AP008K rated 40 A for AC-3 motor duty or AC-1 resistive duty?

A: The 40 A rating of this Siemens contactor applies to AC-3 duty (squirrel cage motor starting and running). For AC-1 (resistive/non-inductive) loads, the current can be up to ~1.3× the AC-3 rating. AC-4 (plugging/reversing) requires significant de-rating — consult the Siemens selection table.

Q: What is the electrical and mechanical life of the 3TS35000AP008K?

A: Siemens contactors are rated for millions of operations: typically 10–30 million mechanical operations and 1–3 million electrical operations at rated current and voltage (AC-3 duty). High-frequency switching applications (>10 operations/hour) require checking the specific thermal capacity of the contactor for continuous duty without overheating.

Q: Can the 3TS35000AP008K be used for reversing duty (forward/reverse motor control)?

A: Contactors used for reversing must be wired with two contactors interlocked so only one can energise at a time. The Siemens series provides mechanical interlock kits that physically prevent both contactors from closing simultaneously — mandatory for reversing and brake applications to prevent phase-to-phase short circuits.

Q: Can multiple 3TS35000AP008K contactors be wired for star-delta starting?

A: Yes. Star-delta starters use three contactors: main (KM1), star (KM2), and delta (KM3). The Siemens contactor series supports mechanical and electrical interlocking accessories that prevent simultaneous energisation of star and delta contactors — critical for safety. Ensure all three contactors are rated correctly for the motor FLC and star-delta transition current.
