AC Modular Contactor

No longer pay for outdated or redundant features. SPX Electric's durable ACAC Modular Contactor is not a single product, but a dynamic ecosystem. It breaks the traditional model of "one function, one device" and integrates power control, signal expansion, logic functions, and state feedback into a reconfigurable platform, bringing you unprecedented design freedom and operational efficiency.

Understand the product

As the power core of the AC Modular Contactor, the basic electromagnetic mechanism can be equipped with dozens of functional modules in a three-dimensional manner around it. Whether it requires an additional 4 sets of auxiliary contacts or a built-in star delta conversion delay module, it only needs to be added at the corresponding position.
Advanced design supports the "online upgrade" of system functions by replacing or upgrading some functional modules through specialized tools without power outage or moving the main circuit.
The modular stacking installation method can save more than 40% of the planar area inside the control cabinet compared to parallel installation of multiple independent components, achieving true high-density layout.
Enterprises only need to reserve standard basic units and universal modules to cover over 90% of application needs, significantly reducing the number of material codes, procurement complexity, and spare parts capital occupation.
When a certain auxiliary function fails, there is no need to disassemble the entire contactor or handle complex wiring harnesses. Only the faulty module needs to be replaced, and the recovery time is measured in minutes.

Product Architecture Deconstruction

The AC Modular Contactor uses an electromagnetic system and silver alloy main contacts to ensure stable switching of the main circuit.

Provide NO/NC auxiliary contacts for controlling circuit interlocking.
Timing function module: Integrated with adjustable delay device to achieve start, stop or interval control.
Safety interlock module: mechanical and electrical dual interlocking, used for safety critical applications such as motor forward and reverse rotation.
State interaction module: including position indication, digital output (DO) status, or fieldbus (such as IO Link) interface.

application

In industrial robots, packaging machinery and other equipment, it is necessary to quickly adjust control logic according to customer orders. The AC Modular Contactor allows for last minute feature configuration before leaving the factory.
To adapt to the production of new products, the production line needs to frequently adjust the workstation functions. Quick changes to the electrical control diagram can be achieved simply by replacing or adding contactor modules.

For example, airport baggage sorting systems and data center backup power switching systems require extremely high availability and rapid maintenance capabilities. Modular design achieves isolation and rapid replacement of faulty parts.
