❓ Frequently Asked Questions

Q: What does the 2 NC (Normally Closed) contact configuration on the 3MT7000-7JA02-6AR2 mean?

A: These contacts change state when the device is operated or energised. Size the contact for the actual switched load — pilot duty ratings are typically lower than the main contact rating.

Q: Can multiple 3MT7000-7JA02-6AR2 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.

Q: What is the electrical and mechanical life of the 3MT7000-7JA02-6AR2?

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 3MT7000-7JA02-6AR2 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.
