- 機械的設置仕様
3.1 取付方法
Two mounting options available:
- DINレール取付 (推奨)
Rail standard: TS35 (35×7.5 mm / 35×15 mm)
手術: Hook the bottom latch onto the rail, press down until an audible click confirms locking. For removal, use a flat screwdriver to pry the bottom latch and lift upwards.
- Base Plate Screw Mounting
Fasten diagonally using 2 × M4 screws; refer to outline drawing for mounting hole spacing.
3.2 取付方向 & クリアランス
- 垂直取り付け (terminals top & 底) 好ましい. 90° horizontal side mounting is permitted; upside-down installation is forbidden.
- Multiple units may be mounted side-by-side without current derating. Maintain ≥15 mm vertical clearance for ventilation; keep away from heat-generating components such as resistors and inverters.
- Avoid installation in high-vibration locations. Vibration acceleration >0.5g requires vibration damping measures.
- Electrical Wiring Specifications
4.1 Terminal Marking Definition
Upper main circuit: L1, L2, L3 (Power Inlet)
Lower main circuit: T1, T2, T3 (Load Outlet)
Non-UL applications allow power feed from top or bottom; UL certified installations require power input from upper L terminals.
Coil terminals A1, A2: Control signal input (AC/DC non-polarized)
補助接点 13-14: Built-in normally open contact (1いいえ)
4.2 ケーブル仕様 & Stripping Length
Standard wire stripping length: 10 mm
Main circuit conductors: Solid/stranded copper cable 1~6 mm²; ferrules recommended for flexible cables
コントロール / auxiliary circuit conductors: 0.75~2.5 mm²
4.3 締付トルク (必須)
主回路端子: 1.5 N・m
コイルA1/A2 & auxiliary contact terminals: 1.2 N・m
Insufficient torque causes terminal overheating; excessive torque leads to thread stripping.
Recommended tools: PZ2 Pozidriv screwdriver / 5.5 mm flat torque screwdriver.
- Critical Coil Application Notes (Core Feature of AF16Z)
- 電圧範囲: AC24~60 V / DC20~60 V, 幅広い電圧互換性, direct drive by PLC DC outputs.
- Very low coil holding power consumption, suitable for long-term energized operation; compliant with SEMI F47 voltage sag immunity requirements.
- A1 and A2 are non-polarized; polarity does not matter for DC24V control.
- Do not apply control voltage exceeding 60 V, otherwise the electronic coil module will be destroyed.
- Optional Accessory Installation
- Side-mounted auxiliary contacts (CA4 series)
Snap-fit onto left/right side slots without tools. 最大 2 sets of side auxiliary contacts can be fitted to AF16.
- 機械的インターロック
Install for reversing circuit configuration of two AF16Z contactors to prevent simultaneous closing and short circuit between forward and reverse phases.
- Thermal overload relay matching
Compatible with TA25DU series thermal relays, direct snap-fit mounting underneath the contactor.
- Commissioning Procedure After Power-On
- Under power-off condition: Visual inspection for correct wiring, no metallic debris, all terminals tightened to specified torque.
- Manually actuate contactor mechanism to confirm smooth operation without jamming.
- Test control circuit independently: Apply rated control voltage to A1/A2; contactor shall pull in reliably and drop out smoothly upon power removal.
- Verify synchronous switching of auxiliary contact 13-14 with contactor operation.
- Connect main circuit for no-load test run; check for abnormal noise and rapid terminal temperature rise.
- 30-minute loaded operation test; recheck terminal temperature to ensure temperature rise stays within allowable limits.
- Installation Faults & Prohibited Practices
❌ Forbidden operations:
Exposed loose strands on cable terminals
Tightening terminals while energized
Control voltage outside the 20~60 V range
Blocking ventilation channels above and below the contactor
Direct installation in environments with combustible dust or continuous condensation
Common Post-Installation Issues
- Contactor chattering/unstable pull-in: Verify control voltage is above minimum operating level; check voltage drop along control cables.
- 端子過熱: Retighten terminals to specified torque; confirm conductor cross-section is adequate.
- Failure to pull in when driven by PLC: Confirm unit is AF16Z (low-power coil); standard AF16 coil cannot be directly driven by PLC transistor outputs.
- メンテナンス要件
- Periodic inspection of terminal temperature and abnormal noise.
- Avoid repeated switching above rated breaking capacity.
- Never operate the contactor with arc shield removed. Replace the complete unit when contacts suffer severe ablation.
Mechanical Life Parameters of ABB AF16Z-30-10-21
The AF16Z shares identical mechanical construction with standard AF16. Official technical data:
✅ Mechanical endurance: 10 100万動作サイクル (10×10⁶演算)
試験条件: 定格制御電圧, no-load switching, standard ambient temperature.
Supporting Key Parameters
- Maximum mechanical operating frequency: 3,600 時間あたりの操作数
Continuous high-frequency operation shall not exceed this limit to avoid accelerated mechanical wear.
- Reference electrical endurance (depends on load type, not equal to mechanical life)
AC-3 (400 V motor load): 約. 1,000,000 サイクル
AC-1 (抵抗負荷): 約. 1,600,000 サイクル
⚠️ Mechanical endurance represents the mechanical operating limit; service life in practical applications is normally determined by electrical erosion of contacts.
Supplementary Remarks
- AF16Z only differs by its low-power electronic wide-range coil variant. Armature, linkage and contact mechanical structure are identical to standard AF16; mechanical endurance ratings remain unchanged.
- Actual mechanical endurance will decrease under harsh environments (重い粉塵, continuous vibration, 高温).
- Definition of mechanical endurance: Operating cycles of contactor pull-in/drop-out driven by coil only, with no load connected to main circuit.
