Description
The AX260-30-11-84 (ABB order No. 1SFL547074R8411) is a heavy-duty 3-pole AC power contactor from ABB’s AX series — the current-generation successor to the legendary AF series, designed for switching large AC motors, capacitor banks, and heavy resistive/heater loads. The “260” denotes the 260A frame size (Ith 250A per IEC 60947-4-1), making it the workhorse for 110–200kW motor control and up to 400A AC-1 non-inductive switching.
- Model breakdown (ABB AX naming):
- AX = AX series power contactor (successor to AF)
- 260 = Frame size 260 — Ith 250A free-air thermal current
- 30 = 3 main poles NO (3 normally-open main contacts, 0 NC)
- 11 = 1 NO + 1 NC auxiliary contact (side-mounted CAL5-11 style, 1NO+1NC)
- 84 = Coil voltage code — 110V AC 50Hz / 110–120V AC 60Hz (per ABB’s official coil code table )
- → AX260-30-11-84 = AX series 260-frame, 3-pole NO main, 1NO+1NC aux, 110V 50Hz / 110-120V 60Hz coil
⚠️ CRITICAL: Coil voltage is 110V, NOT 220V/24V/380V!The “84” coil code = 110V AC (50Hz) or 110–120V AC (60Hz) . This is a common mistake — buyers see “84” and assume 380/220. If your control circuit is 220V AC → you need AX260-30-11-80 (220-230V 50Hz / 230-240V 60Hz). If 24V DC → AX260-30-11-81 (24V). If 380V → AX260-30-11-85. This specific unit (84) ONLY pulls in at 110V AC. Verify your control transformer secondary before ordering!
- Key performance highlights:
- AC-3 rating: 265A @ 380/400V → 132 kW motor switching (per IEC 60947-4-1)
- AC-1 rating: 400A @ 690V — for resistive heaters, capacitor banks, busbar coupling
- Making capacity 10× Ie, breaking capacity 8× Ie — handles severe motor in-rush
- Short-time withstand (Icw): 2120A for 10s, 2650A for 1s — high fault-current tolerance
- Mechanical durability: 5 million operations; electrical: 300 cycles/hour max
- Rated insulation voltage Ui = 690V, impulse withstand Uimp = 8kV — robust dielectric
- Main terminals: Bar-type (ring-tongue crimp lugs) for up to 265A; aux terminals IP40 finger-safe
- Ambient: -40°C to +70°C (storage), -25°C to +55°C with thermal overload relay fitted
- RoHS compliant per EU 2011/65/EU
Typical applications: 110–132kW motor starters (with overload relay TAxxx), capacitor bank switching (up to 400A AC-1), induction heating/curing ovens, crusher/compressor/mill main contactors, marine/ offshore 440V 60Hz motor control (the 110-120V 60Hz coil is ideal for US/Asian 60Hz control circuits stepping up from 120V control power).
💡 Why AX260 over AF260? AX is the direct replacement for the legacy AF260 — same dimensions (140×180×225mm), same terminal layout, same coil codes. If you’re maintaining an older AF260-30-11-84, the AX260-30-11-84 drops in mechanically and electrically identical (ABB confirmed backward compatibility). The AX adds improved coil energy efficiency and extended mechanical life (5M vs AF’s 4M).

Warranty & After-Sales
- Factory new units: 12 months warranty
- Refurbished units: 3-6 months warranty (bench: 110V AC applied to coil → clean pull-in @ ≤75ms, drop-out @ ≤25ms, contact resistance <0.5mΩ main poles, auxiliary contact continuity verify, mechanical 5× manual operate)
- Technical support for:
- Coil voltage confirmation (84 = 110V 50Hz / 110-120V 60Hz — CRITICAL; if your control circuit is 220V → AX260-30-11-80; if 24V → -81; we can cross-all-coil-codes on AX260 frame)
- AF260 → AX260 migration (AX260-30-11-84 is the drop-in replacement for legacy AF260-30-11-84 — identical dimensions 140×225×180mm, same bar terminals, same coil code, 5M vs 4M mechanical life; no panel rewiring needed)
- Overload relay pairing (recommended thermal O/L: TAxxx-260 series — TA200-260 or electronic overload EFxxx; mounted directly to contactor left-side, CAL5-11 aux provides trip signal to coil)
- Interlock / reversing setup (for motor reversing: pair two AX260-30-11-84 with mechanical interlock AX-IM… kit + electrical interlock via auxiliary NC; prevent simultaneous close)
- Capacitor switching duty (AX series rated for capacitor banks; for 400A AC-1 @ 690V resistive/capacitive — derate per ABB 1SBC100214C0202 manual if switching >1000A reactive)
- Terminal torque specs (main bar terminals: M10 bolt, torque 25 N·m typical; aux terminal: 0.8 N·m; improper torque → overheating, contact failure)
- 60Hz vs 50Hz coil (84 code covers BOTH 50Hz 110V and 60Hz 110-120V — universal coil, works globally on 110V control circuits regardless of mains frequency; no need to specify Hz when ordering “84”)
- Optional: Matching overload relays (TA200-260, EFxxx), mechanical interlock kits (AX-IM), suppressor modules (RC snubber for inductive control circuit), 110V control transformer, bar terminal crimp lugs (M10), contactor mounting plate (DIN rail adapter for AX frame)

Applications
- 110–132kW Motor Starter (Mining/Cement/Power Plant): AX260-30-11-84 as main contactor in star-delta or DOL starter for 132kW/400V motor (crusher, mill, compressor, pump). Paired with TA200-260 overload relay + 110V control transformer. 10× Ie making capacity handles 2650A motor in-rush cleanly. Mechanical life 5M ops = years of maintenance-free service.
- Capacitor Bank Switching (LV PFC): 400A AC-1 @ 690V capability — switches large capacitor stages in power factor correction panels. Side-mounted 1NO+1NC aux provides “capacitor energized” feedback to controller. 8kV impulse withstand survives capacitor discharge transients.
- Marine / Offshore 440V 60Hz: Ships and offshore platforms use 440V 60Hz mains with 110-120V 60Hz control circuits — this 84 coil is perfect (110-120V 60Hz per ABB code). Switches 265A @ 440V = 160kW motors onboard. IP40 aux + -25°C to +55°C operating range handles marine environment.
- US/Canada Industrial 460V 60Hz: North American plants run 460V 60Hz motors with 120V control — AX260-30-11-84’s 110-120V 60Hz coil matches the 120V control power exactly. 250A @ 500V = 160kW motor switching for pumps, blowers, conveyors.
- Resistive Heater / Induction Furnace: Up to 400A AC-1 @ 690V = 400A × 690V × √3 ≈ 478kW resistive load. Single AX260-30-11-84 replaces multiple smaller contactors in parallel. Bar terminals accept up to 400A crimp lugs.
- AF260 Legacy Replacement: Existing AF260-30-11-84 in 10-year-old panel — AX260-30-11-84 is 100% drop-in (dimensions, terminals, coil code identical). Swap in 5 minutes during planned maintenance. Extended 5M mechanical life vs AF’s 4M.
