Main Models in the Same Series
All below front-mount auxiliary contacts of CA5X series fit AX series contactors, differing mainly in contact configuration:
| Полная модель | Конфигурация контактов | Part No. | Основное приложение |
| CA5X-10 | 1НЕТ | 1SBN019010R1010 | Single NO contact for basic operating status feedback |
| CA5X-01 | 1Северная Каролина | 1SBN019010R1001 | Single NC contact for safety interlock and stop signal feedback |
| CA5X-11 | 1НО+1НЗ | 1SBN019010R1011 | 1NO+1NC for general control circuit expansion |

| CA5X-02 | 2Северная Каролина | 1SBN019010R1002 | Dual NC contacts for redundant safety circuit design |
> Важное примечание: CA5X series is only compatible with AX / NX series contactors. For legacy A/AL/AE series contactors, please use CA5 series auxiliary contacts (например. CA5-10). The two series feature incompatible mechanical structures and must not be used interchangeably.
Compatible Contactors
Main contactors: ABB AX series AC contactors (Full range: AX06 ~ AX150)
Реле: ABB NX series contact relays
Stacked installation: До 4 pieces of CA5X auxiliary contact blocks can be mounted on the front of one single contactor.
Установка & Инструкции по подключению
- Этапы установки: Cut off power supply first. Align the auxiliary contact block with the guide grooves on the contactor front, then press down vertically until an audible click indicates full locking. Shake slightly to confirm firm installation. To remove, press the release latch on the top and pull upwards.
- Определение терминала: Terminals marked “3” и “4” correspond to the two ends of the single NO contact. The contact closes when the contactor is energized and opens when de-energized.
- Спецификация проводки: Suitable for solid/stranded wires of 0.5~1.5mm² and flexible wires of 0.5~1.0mm². Tighten screws at 0.6~0.8 N·m to avoid terminal damage or poor contact caused by excessive torque.
- Prohibited Operations: Never install or remove the block while powered on. It is designed exclusively for control circuit signals and shall not be connected to main power circuits for load switching. Do not operate continuously beyond rated load.
Troubleshooting Matrix
| Явление неисправности | Root Cause | Step-by-Step Solutions |
| Contact fails to close when contactor is energized | Improper installation, contact oxidation or loose wiring | 1. Reinstall the block after power off and ensure full locking of clips. |
| 2. Retighten terminals and check wire continuity. | ||
| 3. Operate the contactor repeatedly to polish contacts; replace the block if severely oxidized. | ||
| Плохой контакт & flickering signals | Insufficient screw torque, terminal oxidation or overload | 1. Retighten terminals to specified torque. |
| 2. Clean contact surfaces to remove oxide layer. | ||
| 3. Verify load current and ensure compliance with AC-15 / DC-13 ratings. | ||
| Contactor jams and cannot pull in after installation | Misaligned block, incomplete clip engagement or foreign debris | 1. Remove and reinstall the block with proper alignment to guide grooves. |
| 2. Clean dust and foreign objects between contactor and block. | ||
| 3. Inspect for deformation; replace the block if structural damage is found. | ||
| Abnormal overheating at terminals during operation | Ослабленное соединение, insufficient wire gauge or circuit overload | 1. Reconnect wires and ensure full insertion of conductors into terminals (power off). |
| 2. Confirm wire cross-section matches load current. | ||
| 3. Check circuit current; prolonged overload operation is forbidden. |
Both CA5-10 and CA5X-10 are front-mount auxiliary contacts with 1 нормально открытый контакт. They share nearly identical electrical parameters but belong to two generations of contactor platforms with completely incompatible mechanical mounting structures, and must never be mixed. CA5-10 matches legacy A series contactors, while CA5X-10 is dedicated to the new AX series.

- Key Differences Analysis
2.1 Fundamental Difference: Non-interchangeable Mechanical Interface
The two models are similar in appearance and overall size, but differ in clip grooves and linkage structures, which are designed for dedicated contactor housings respectively:
Clips of CA5-10 fit exclusive grooves on A series contactors.
Clips of CA5X-10 match the new interface of AX series contactors.
Forced assembly will lead to loose clips, out-of-sync contacts and contactor jamming, and may even damage internal mechanisms. This is strictly prohibited in selection and application.
2.2 Product Generation & Supply Positioning
CA5-10: Mature legacy product, mainly used for maintenance and replacement of existing A series contactors. Not recommended for new projects.
CA5X-10: Current flagship product of ABB, supporting AX series contactors (successor of legacy A series). It features stable stock and comprehensive technical support.
2.3 Identical Electrical Performance & Compatible Circuit Design
They adopt the same technical platform for contact materials, arc extinguishing structures and electrical parameters. Load capacity and service life are equivalent under the same utilization category. Control circuit design and wiring rules can be fully followed between each other.
- Выбор & Рекомендации по замене
- Maintenance of Existing Equipment: If the original contactors are A/AL/AE/AF series, select CA5-10 exclusively. CA5X-10 cannot be used as a replacement.
- Новый дизайн проекта: Prioritize the combination of AX series contactors + CA5X series auxiliary contacts. This is ABB’s mainstream solution with reliable long-term supply and after-sales service.
- Contact Configuration Expansion: Both series provide multiple contact types such as CA5X-01/11/20/02 with consistent naming rules. Select models according to NO/NC requirements of control circuits.
