2.3 Rating Summary Table

3. Especificaciones de instalación mecánica

3.1 Métodos de montaje

Two mounting options available:

1. Montaje en carril DIN (Recomendado)

Rail standard: TS35 (35×7.5 mm / 35×15 mm)

Operación: 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.

2. Base Plate Screw Mounting

Fasten diagonally using 2 × tornillos M4; refer to outline drawing for mounting hole spacing.

3.2 Orientación de montaje & Autorización

1. Montaje vertical (terminals top & abajo) privilegiado. 90° horizontal side mounting is permitted; upside-down installation is forbidden.
2. 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.
3. Avoid installation in high-vibration locations. Vibration acceleration >0.5g requires vibration damping measures.
4. Especificaciones de cableado eléctrico

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)

Contacto auxiliar 13-14: Built-in normally open contact (1NO)

4.2 Especificación del cable & Longitud de pelado

Longitud de pelado de cables estándar: 10 milímetros

Main circuit conductors: Solid/stranded copper cable 1～6 mm²; ferrules recommended for flexible cables

Control / auxiliary circuit conductors: 0.75~2,5 mm²

4.3 Par de apriete (Obligatorio)

Terminales del circuito principal: 1.5 Nuevo Méjico

Bobina A1/A2 & auxiliary contact terminals: 1.2 Nuevo Méjico

Insufficient torque causes terminal overheating; excessive torque leads to thread stripping.

Recommended tools: PZ2 Pozidriv screwdriver / 5.5 mm flat torque screwdriver.

5. Critical Coil Application Notes (Core Feature of AF16Z)
6. Rango de voltaje: AC24～60 V / DC20～60 V, amplia compatibilidad de voltaje, direct drive by PLC DC outputs.
7. Very low coil holding power consumption, suitable for long-term energized operation; compliant with SEMI F47 voltage sag immunity requirements.
8. A1 and A2 are non-polarized; polarity does not matter for DC24V control.
9. Do not apply control voltage exceeding 60 V, otherwise the electronic coil module will be destroyed.
10. Optional Accessory Installation
11. Contactos auxiliares laterales (CA4 series)

Snap-fit onto left/right side slots without tools. Máximo 2 sets of side auxiliary contacts can be fitted to AF16.

2. Enclavamiento mecánico

Install for reversing circuit configuration of two AF16Z contactors to prevent simultaneous closing and short circuit between forward and reverse phases.

3. Thermal overload relay matching

Compatible with TA25DU series thermal relays, direct snap-fit mounting underneath the contactor.

7. Commissioning Procedure After Power-On
8. Under power-off condition: Visual inspection for correct wiring, no metallic debris, all terminals tightened to specified torque.
9. Manually actuate contactor mechanism to confirm smooth operation without jamming.
10. Test control circuit independently: Apply rated control voltage to A1/A2; contactor shall pull in reliably and drop out smoothly upon power removal.
11. Verify synchronous switching of auxiliary contact 13-14 with contactor operation.
12. Connect main circuit for no-load test run; check for abnormal noise and rapid terminal temperature rise.
13. 30-minute loaded operation test; recheck terminal temperature to ensure temperature rise stays within allowable limits.
14. 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

1. Contactor chattering/unstable pull-in: Verify control voltage is above minimum operating level; check voltage drop along control cables.
2. Terminal overheating: Vuelva a apretar los terminales al par especificado; confirm conductor cross-section is adequate.
3. Failure to pull in when driven by PLC: Confirm unit is AF16Z (bobina de baja potencia); standard AF16 coil cannot be directly driven by PLC transistor outputs.
4. Requisitos de mantenimiento
5. Periodic inspection of terminal temperature and abnormal noise.
6. Avoid repeated switching above rated breaking capacity.
7. 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 millones de ciclos de funcionamiento (10×10⁶ operaciones)

Condiciones de prueba: Tensión de control nominal, conmutación sin carga, standard ambient temperature.

Supporting Key Parameters

1. Maximum mechanical operating frequency: 3,600 operaciones por hora

Continuous high-frequency operation shall not exceed this limit to avoid accelerated mechanical wear.

2. Reference electrical endurance (depends on load type, not equal to mechanical life)

AC-3 (400 V motor load): Aprox.. 1,000,000 ciclos

AC-1 (carga resistiva): Aprox.. 1,600,000 ciclos

⚠️ Mechanical endurance represents the mechanical operating limit; service life in practical applications is normally determined by electrical erosion of contacts.

Observaciones complementarias

1. 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.
2. Actual mechanical endurance will decrease under harsh environments (polvo pesado, continuous vibration, temperatura alta).
3. Definition of mechanical endurance: Operating cycles of contactor pull-in/drop-out driven by coil only, with no load connected to main circuit.
