    Operating principle

    A 24V DC voltage is applied to the contactor's control coil. The coil generates a magnetic field that attracts the contactor mechanism and closes the three main power contacts. This switches on the connected three-phase load, such as an electric motor, fan, pump, or heating unit.

    When the 24V DC control voltage is removed from the coil, the contactor mechanism returns to its original position, the main contacts open, and the load is switched off. The integrated 1NC auxiliary contact can be used for signaling, interlocking, automatic control, or monitoring the contactor's status in the control circuit.

    When is a 24V DC coil needed?
    A 24V DC control coil is used in automation systems, PLC controller circuits, control cabinets, safe low-voltage control schemes, and other systems where the contactor is controlled by a constant 24V voltage.

    Where is it used?

    • Electric motor control – for smaller three-phase motors, pumps, fans, and drives.
    • Automation cabinets – in PLC, relay, sensor, and 24V DC control systems.
    • Ventilation systems – for controlling air supply, exhaust, and technical fans.
    • Heating systems – for controlling electric heaters, heating sections, and other loads.
    • Lighting control circuits – to switch lighting groups on or off based on time, sensors, or automation signals.
    • Industrial equipment – in mechanisms, packaging equipment, production lines, and control panels.

    Practical installation example

    For example, the contactor is installed in an electrical control cabinet and used to control a 2.2 kW three-phase fan. The control coil is connected to a 24V DC PLC output or control relay, and the power contacts are wired between a circuit breaker and a motor protection relay or directly, according to the specific electrical schematic.

    When the automation system activates the 24V DC signal, the contactor switches on the fan's power supply. The integrated 1NC auxiliary contact can be used for control interlocking, contactor interlocks, or to send a status signal to the controller.

    Usage by user type

    Electrician: a compact contactor suitable for installation in control cabinets, automation panels, motor control circuits, and other systems where 24V DC control is used.

    Automation engineer: a convenient solution for PLC and relay control systems when reliable three-phase load switching and an additional 1NC contact for interlocking or status signaling are required.

    Industrial companies: can be used for controlling ventilation, pumps, small drives, heating systems, production equipment, and other electrical loads.

    Maintenance technician: a practical choice when replacing a worn-out contactor of the same type or upgrading existing control cabinets that require a 24V DC coil and 1NC auxiliary contact.

    Pros

    • 3P contactor – suitable for controlling three-phase loads.
    • 9A AC-3 / AC-3e – suitable for smaller electric motors and other inductive loads.
    • 24V DC coil – compatible with most automation and PLC control systems.
    • 1NC auxiliary contact – useful for interlocking, signaling, or control logic.
    • Compact TeSys K series – convenient for control cabinets with limited space.
    • Screw terminals – standard and reliable wire connection.
    • Up to 690V AC power circuit – can be used in various low-voltage electrical systems, adhering to rated utilization categories.
    • Schneider Electric manufacturer – widely used industrial automation component series.

    Cons / limitations

    • Control coil 24V DC only – not suitable for direct 230V AC or other voltage control.
    • 9A AC-3 current – not suitable for larger motors requiring higher current contactors.
    • 1NC auxiliary contact – if additional NO or NC contacts are needed, an auxiliary contact block may be required.
    • Requires proper protection – the contactor is not a motor protection device; appropriate protections must be selected in the circuit.
    • Requires correct schematic – contactor application depends on the load, control logic, and specific installation conditions.

    Safety and installation notes

    The contactor is an electrical control component, therefore its installation and connection must be performed according to the electrical schematic, manufacturer documentation, and applicable electrical safety requirements.

    • Installation must be performed by a qualified electrician experienced with electrical control and power circuits.
    • Before installation, it is mandatory to disconnect power and verify that there is no voltage in the circuit.
    • Coil voltage must be 24V DC only – connecting incorrect voltage may cause the contactor to fail.
    • Proper protection is mandatory in the motor circuit – a circuit breaker, fuses, and, when necessary, a thermal motor protection relay.
    • Wire cross-section and protective devices must be selected based on actual load current, cable length, and installation conditions.
    • The purpose of the 1NC auxiliary contact must be verified against the specific control schematic before connection.

    Suitable when you need:
    • to control a smaller three-phase motor up to a typical power of 2.2 kW at 400V AC-3;
    • to use a 24V DC PLC, relay, or automation signal;
    • an integrated 1NC auxiliary contact;
    • a compact contactor for a control cabinet with limited space;
    • to control a fan, pump, heating unit, or other three-phase load.
    Check before ordering:
    • if the control circuit truly uses 24V DC voltage;
    • if the actual load current does not exceed 9A in the AC-3 category;
    • if additional auxiliary contacts are needed;
    • if the contactor will be used for a motor, heating, or other type of load;
    • if the system includes appropriate overload and short-circuit protection.
    Important reminder:
    The contactor is not a full motor protection device. Depending on the project, the motor control circuit may require a circuit breaker, fuses, a thermal protection relay, a phase monitoring relay, and other protection and control components.

    FAQ – Frequently asked questions

    Is this contactor suitable for a three-phase motor?
    Yes, the contactor has three main power poles and is designed for controlling three-phase loads. Its rated current in the AC-3 category is 9A, and at 400V, the typical motor power is up to 2.2 kW. Final selection must be based on the specific motor's rated current and starting conditions.
    What does a 24V DC coil mean?
    It means that the contactor's control terminals require a 24V DC supply. Once this voltage is received, the coil engages the main power contacts of the contactor.
    What does a 1NC auxiliary contact mean?
    1NC means one normally closed auxiliary contact. When the contactor is in its resting state, this contact is closed, and when the contactor is energized, it opens. It can be used for interlocking, signaling, or control logic.
    Can the contactor be controlled from a PLC?
    Yes, if the PLC or intermediate relay can reliably provide a 24V DC control signal and the output current and control schematic match the requirements of the contactor coil.
    Does the contactor have motor overload protection?
    No. The contactor only switches the load on or off. For motor overload protection, an additional thermal protection relay, motor protection circuit breaker, or other appropriately selected protection is usually used.
    Can the contactor be used for lighting control?
    Yes, it can be used to control lighting groups, but it is necessary to evaluate the actual type of load, the inrush currents of LED power supplies, and the utilization category. For larger LED lighting projects, specifically designed contactors might be required.
