- In-Depth Operating Principle
AF-series contactors adopt electronic rectifier-type coil, different from traditional AC contactors:
- Apply 100-250 V AC or DC to A1/A2; internal electronic circuit rectifies input to DC for driving electromagnetic coil.
- High instantaneous power for pull-in, then switch to low DC holding power; much lower coil heating than conventional AC coils.
- On-board built-in TVS surge absorber dissipates back-EMF upon coil de-energization. Do NOT connect external RC networks or varistors in parallel; external devices may cause malfunction or permanent damage.
- DC-magnetized armature eliminates 50 Hz AC hum noise.

- Risoluzione dei problemi
| Sintomo | Causa ultima | Rimedio |
| Contactor will not pull‑in | No voltage across A1‑A2; loose connections; internal electronic coil board failure | Measure voltage A1‑A2; retighten terminals; replace complete unit (AF coil cannot be replaced separately) |
| Chattering / intermittent pull‑in | Control voltage below 80 % minimum limit; excessive power‑supply ripple | Ensure input voltage ≥80 V; rule out insufficient PLC output drive capacity |
| Excessive main‑circuit terminal heating | Insufficient bolt torque; sovraccarico; erosione da contatto / burning | Retorque busbar bolts; check load current; replace contactor for severe contact ablation |
| Contacts remain closed after de‑energization (sticking) | Saldatura dei contatti principali; residual induced voltage on control wiring | Investigate short‑circuit conditions on load side; eliminate induced residual voltage in control cables |
Important: The AF-series coil electronic board is integrated inside the unit; coil faults require complete contactor replacement; spare coil assemblies are not available.

- Specifiche di installazione
- Orientamento di montaggio: vertical upright installation only (main terminals vertical up-down). Sideways or inverted mounting is strictly forbidden.
- Two installation options:
Back-plate screw fixing: 4 pcs M8 bolts
DIN35 mm rail mounting (For large-frame AF265, screw mounting is preferred over rail-mount).
- Cabinet heat dissipation: Multiple units can be mounted side-by-side without gaps; no derating up to 70 ℃ ambient. Derating is mandatory for altitude >3000 m.
- Suggested minimum cabinet dimension: ≥900×750×300 mm, to ensure adequate top-bottom ventilation.
- Prevent metal chips and drilling dust from entering contactor enclosure during installation.
- Cablaggio & Coppia di serraggio (Most overheating originates from insufficient torque)
| Terminal Location | Bolt Size | Recommended Tightening Torque | Requisiti dei cavi |
| Main circuit L/T terminals | M12 | 24 N·m | Copper busbar / ATK300 lugs; 75 ℃ rated copper conductors; direct aluminum conductor connection prohibited |
| Coil A1‑A2 | M4 | 1.2‑1.5 N·m | 0.75‑2.5 mm² copper wire |
| Contatti ausiliari | M4 | 1.2 N·m | 0.75‑2.5 mm² copper wire |
ATK300 crimped lugs are recommended for main circuit. Fit AF-MTP terminal safety shield over bare live conductors for touch-protection.
- Coil Operating Instructions (AF Electronic Coil Key Notes)
- A1/A2 coil terminals are non-polar; either AC or DC 100-250 V may be applied directly.
- Built-in on-board TVS surge suppression. External RC snubber, varistor or freewheeling diode are strictly forbidden. External surge devices will burn coil board or cause failure to open.
- Accoglienza: reliable closing ≥80 % ×100 V = 80 V.
- Ritirarsi: reliable opening ≤55 %Uc.
- Low holding power consumption; silent operation, no hum.
- ❗Electronic coil board is integrated within main unit. Coil cannot be replaced separately; full-unit replacement required upon coil failure.
- Dielectric withstand test: Never perform hipot test across A1-A2 coil terminals; will destroy electronic circuit.
- Passaggi di messa in servizio
- All power disconnected; verify full wiring and torque values; confirm arc-chamber cover is fully seated and intact.
- Confirm control supply voltage matches -13 coil rating (100-250 VAC/DC).
- Keep main 3-phase supply disconnected; energize only control circuit for no-load functional test:
Apply voltage to A1-A2: contactor shall pull-in promptly; de-energize for immediate release without chattering.
Verify auxiliary contact logic: 13-14 open/close, 21-22 close/open as expected.
- Proceed to energize main power only after successful no-load test, perform loaded trial-run.
- Run under full load for minimum 30 minutes; measure terminal temperature rise; acceptable housing temperature rise ≤60 K.
- Accessory Mounting
- CAL19-11 (side-mount auxiliary block): Slide into left-hand side slot of contactor until fully latched; adds 1NO+1NC contacts.
- VM265 mechanical interlock: for forward-reverse interlock application; two contactors required as pair.
- TA275-DU thermal overload relay: bottom-mount installation; relay operating temperature range -25~+55 ℃.
- AF-MTP main-circuit terminal safety shield, prevents accidental touch of live busbars.
All accessories are separately-ordered, not included as standard delivery.
- Manutenzione periodica & Ispezione
Perform only with full power disconnected! Maintenance interval: every 12 months for clean environment; every 6 months for dusty / high-vibration conditions.
- Retighten all main-circuit terminals to specified torque.
- Inspect arc-chamber cover for cracks, carbon deposits or metal powder accumulation; replace arc-chamber for severe burning.
- Inspect main contact erosion; replace complete unit for heavy wear or contact welding. No separate contact spare-parts available for AF265.
- Clean external dust. Do NOT blow compressed-air directly into enclosure, metal dust may damage internal coil electronics.
- Verify cabinet ambient temperature and unobstructed ventilation paths.
- Functional test of auxiliary contact switching.
Nota: AF190-AF370 frame units have no serviceable separate contact assemblies; full-unit replacement required upon contact damage.
