1. Core Electrical Specifications

III. Environmental & Mechanical Parameters

Certifications: CCC, CE, UKCA, EAC, DNV marine certification; Functional safety: SIL2, ISO13849-1 Cat.B.

1. In-Depth Operating Principle

AF-series contactors adopt electronic rectifier-type coil, different from traditional AC contactors:

1. Apply 100-250 V AC or DC to A1/A2; internal electronic circuit rectifies input to DC for driving electromagnetic coil.
2. High instantaneous power for pull-in, then switch to low DC holding power; much lower coil heating than conventional AC coils.
3. 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.
4. DC-magnetized armature eliminates 50 Hz AC hum noise.

Separately-ordered Accessories

1. Cross-Brand Compatibility & Replacement Reference

⚠️Verify coil rating 100-250 VAC/DC and AC-3 265 A rating before replacement.

VII. Typical Application Scenarios

1. Fan & pump large-size motor starting (HVAC, central air-conditioning, water treatment)
2. Air compressor, extruder motor control (110-132 kW three-phase motors)
3. Capacitor bank switching (match AC-1 400 A rating)
4. Forward/reversing and star-delta main circuits
5. Marine & export-oriented equipment: compatible with global control voltages (120 VAC /220 VAC universal)

VIII. Selection Pitfalls & Hard Restrictions

1. ❌Do NOT add external surge suppressors (RC networks, varistors, diodes). Built-in surge protection provided; external devices cause coil damage or failure to open.
2. ❌Sideways or inverted mounting forbidden; only upright vertical installation permitted.
3. ❌Derating is mandatory above 3000 m altitude; otherwise contact overheating and burnout may occur.
4. ❌Not suitable for high-frequency switching (>300 operations/hour); use vacuum contactors for frequent-duty applications.
5. ✅Wide control voltage tolerance: reliable pull-in within 80-250 V.
6. Troubleshooting

Important: The AF-series coil electronic board is integrated inside the unit; coil faults require complete contactor replacement; spare coil assemblies are not available.

12. Product Overview

AF265-30-11-13 is a 3-pole contactor with integrated wide-range electronic coil and built-in surge suppression. External RC / varistor suppressors are prohibited.

AC-3-400 V: 265 A, motor rating 132 kW

AC-1 resistive: 400 A

Built-in auxiliary contacts:1NO(13-14)+1NC(21-22)

Coil rating:100-250 V AC/DC; pull-in ≥80 %Uc; drop-out ≤55 %Uc

Mechanical endurance:5 million cycles; max operating frequency 300 operations/hour

Operating temperature:-40 ℃~+70 ℃ (without thermal relay); no derating ≤3000 m altitude.

2. Terminal Definition

CAL19-11 auxiliary add-on block can be fitted on the left side of unit.

3. Installation Specifications
4. Mounting orientation: vertical upright installation only (main terminals vertical up-down). Sideways or inverted mounting is strictly forbidden.
5. 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).

3. 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.
4. Suggested minimum cabinet dimension: ≥900×750×300 mm, to ensure adequate top-bottom ventilation.
5. Prevent metal chips and drilling dust from entering contactor enclosure during installation.
6. Wiring & Tightening Torque (Most overheating originates from insufficient torque)

ATK300 crimped lugs are recommended for main circuit. Fit AF-MTP terminal safety shield over bare live conductors for touch-protection.

5. Coil Operating Instructions (AF Electronic Coil Key Notes)
6. A1/A2 coil terminals are non-polar; either AC or DC 100-250 V may be applied directly.
7. 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.
8. Pull-in: reliable closing ≥80 % ×100 V = 80 V.
9. Drop-out: reliable opening ≤55 %Uc.
10. Low holding power consumption; silent operation, no hum.
11. ❗Electronic coil board is integrated within main unit. Coil cannot be replaced separately; full-unit replacement required upon coil failure.
12. Dielectric withstand test: Never perform hipot test across A1-A2 coil terminals; will destroy electronic circuit.
13. Commissioning Steps
14. All power disconnected; verify full wiring and torque values; confirm arc-chamber cover is fully seated and intact.
15. Confirm control supply voltage matches -13 coil rating (100-250 VAC/DC).
16. 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.

4. Proceed to energize main power only after successful no-load test, perform loaded trial-run.
5. Run under full load for minimum 30 minutes; measure terminal temperature rise; acceptable housing temperature rise ≤60 K.
6. Accessory Mounting
7. CAL19-11 (side-mount auxiliary block): Slide into left-hand side slot of contactor until fully latched; adds 1NO+1NC contacts.
8. VM265 mechanical interlock: for forward-reverse interlock application; two contactors required as pair.
9. TA275-DU thermal overload relay: bottom-mount installation; relay operating temperature range -25~+55 ℃.
10. AF-MTP main-circuit terminal safety shield, prevents accidental touch of live busbars.

All accessories are separately-ordered, not included as standard delivery.

8. Periodic Maintenance & Inspection

Perform only with full power disconnected! Maintenance interval: every 12 months for clean environment; every 6 months for dusty / high-vibration conditions.

1. Retighten all main-circuit terminals to specified torque.
2. Inspect arc-chamber cover for cracks, carbon deposits or metal powder accumulation; replace arc-chamber for severe burning.
3. Inspect main contact erosion; replace complete unit for heavy wear or contact welding. No separate contact spare-parts available for AF265.
4. Clean external dust. Do NOT blow compressed-air directly into enclosure, metal dust may damage internal coil electronics.
5. Verify cabinet ambient temperature and unobstructed ventilation paths.
6. Functional test of auxiliary contact switching.

Note: AF190-AF370 frame units have no serviceable separate contact assemblies; full-unit replacement required upon contact damage.
