ABB contactor​ AX09-30-10-80

The ABB contactor **AX09-30-10-80** is an AC contactor in the AX series, mainly used for the starting of motors in the industrial control field, the switching on and off of power circuits, and automation systems. The following is a detailed analysis of its core parameters, functional features, and application scenarios:

 I. Model Analysis and Core Parameters

1. **Model Structure**

   - **AX**: Represents the AX series contactor of ABB, suitable for the control of medium and small power motors.

   - **09**: The rated operating current is **9A** (in the AC-3 category, it can control a 3.7kW motor at 400V).

   - **30**: The main contact configuration is **3 normally open poles (3NO)**, used for connecting three-phase loads.

   - **10**: The auxiliary contact is **1 normally open (1NO)**, which can be used for signal feedback or interlocking control.

   - **80**: The coil voltage is **220-230V AC (50Hz)** or **230-240V AC (60Hz)**, which is compatible with the grid voltages of most regions around the world.

2. **Key Technical Parameters**

   - **Rated Voltage**: The main circuit is **690V AC**, and the control circuit is **220-240V AC**.

   - **Conventional Heating Current**: **24A** (the maximum current for long-term operation).

   - **Electrical Life**: Up to **1 million times** (under AC-3 load).

   - **Protection Level**: **IP20**, which can prevent fingers from touching the internal live parts.

   - **Ambient Temperature**: From -40°C to +70°C, adapting to a wide-temperature industrial environment.

 II. Functional Features and Design Advantages

1. **Modular Design*YouTube ：https://youtube.com/shorts/xxa1_LojNMQ  *

   - It supports **front-mounted or side-mounted accessories**, such as auxiliary contact modules (CA5 series), timers (TEF5), interlocking kits (VM5/VE5), etc., and the functions can be flexibly expanded.

   - Models below 185A support **maintenance without disconnecting wires**, allowing the coil to be replaced or the contacts to be inspected without disassembling the main circuit, reducing the downtime.

2. **Safety and Certification**

   - It complies with **CCC, CE, RoHS** certifications, and some models have passed the **UL certification** (the specific model needs to be confirmed).

   - It has a built-in **arc extinguishing chamber**, and the arcing distance is zero, so it can be directly installed near the door panel of the control cabinet.

3. **Application Scenarios**

   - **Industrial Field**: Control of medium and small motors (such as conveyors, fans, water pumps), and auxiliary circuits of electric locomotives.

   - **Building and Building**: Lighting systems, air conditioning compressors, and automatic door control.

   - **New Energy**: Switch control of photovoltaic inverters and energy storage systems.

 III. Market Information and Purchase Suggestions

1. **Supply Status**

   - This model is still in stock in 2025 and can be purchased through platforms such as Alibaba and eBay. The price is approximately **29.78 yuan to 55 Australian dollars** (there are differences in different channels and regions).

   - Some suppliers provide **customization services**, such as coil voltage adjustment or special certifications (such as UL).

2. **Alternative Models**

   - If a higher current rating is required, **AX12-30-10-80 (12A)** or **AX18-30-10-80 (18A)** can be considered.

   - If a DC coil is required, the AX series also has versions such as **DC 24V, 48V** (such as AX09-30-10-36*190V).

3. **Purchase Precautions**

   - Confirm the **coil voltage and frequency** (such as 50Hz or 60Hz) to avoid burning the coil due to voltage mismatch.

   - For the US market, it is necessary to confirm whether the product has passed the **UL certification**, and you can query it by entering the certificate number (such as E333333) on the UL official website.

IV. Typical Application Cases

1. **Motor Control**

   - It is used for the direct starting of a **3.7kW three-phase motor** and cooperates with a thermal relay (such as the TA series) to achieve overload protection.

   - It supports **star-delta step-down starting**, and the winding switching is realized through the auxiliary contacts.

2. **Lighting System**

   - It controls the switching on and off of the **LED lighting distribution box** and is compatible with PWM dimming signals.

   - It is integrated with ABB's i-bus system to achieve intelligent lighting management.

3. **New Energy Field**

   - As a DC contactor in the **photovoltaic inverter**, it controls the charging and discharging of the battery pack.

   - In the **energy storage system**, it is used for busbar switching to ensure the safe operation of the system.
