The Siemens 3RT1466-6AP368K is a 3-pole power contactor from the Siemens SIRIUS 3RT range, designed for switching electrical loads in industrial control, automation and power-distribution applications. This model is specified for AC-1 duty and includes Remaining LifeTime indication, helping maintenance teams monitor the contactor's service condition. Available product listings identify this article as a 3-pole AC-1 contactor with a 400 A rating and 220–240 V AC/DC coil, with 2NO + 2NC auxiliary contacts.
The 3RT1466-6AP368K is designed for switching three-phase electrical loads in industrial systems.
A power contactor allows a relatively small control signal to operate a larger electrical load through its main contacts. This makes it suitable for centralized and automated switching applications.
Typical applications include:
The application must be matched to the contactor's utilization category and electrical ratings.
The 3RT1466-6AP368K is specified for AC-1 duty.
AC-1 applications generally involve loads with relatively non-inductive or only slightly inductive characteristics, such as resistive heating loads and certain distribution applications.
Typical AC-1 uses can include:
The contactor should be selected according to the actual load characteristics and applicable utilization category.
A notable feature of the 3RT1466-6AP368K is its Remaining LifeTime indication.
This feature can help maintenance personnel assess the service condition of the contactor and plan replacement before end-of-service conditions become a problem.
Potential benefits include:
For industrial facilities with continuous or critical operation, remaining-life information can help maintenance teams make more informed decisions.
Available product information identifies this model with 2NO + 2NC auxiliary contacts.
Auxiliary contacts can be used for:
The actual auxiliary-contact arrangement should always be verified against the product documentation before designing the control circuit.
The 3RT1466-6AP368K is listed with a 220–240 V AC/DC coil, allowing the contactor to be used with compatible control circuits using the specified coil supply.
This can be useful in industrial control panels where the contactor is controlled by relays, PLC outputs or other suitable control devices.
The control supply must always be matched to the manufacturer's specified coil requirements.
Product listings identify the 3RT1466-6AP368K as a 400 A AC-1, 3-pole power contactor.
Its high-current switching capability makes it suitable for large industrial loads where a robust contactor is required.
Potential applications include:
Correct load selection, protection coordination and installation practices are essential for safe operation.
The contactor can be integrated into larger industrial control systems using suitable control and monitoring components.
A typical arrangement may include:
PLC / Control System → Contactor Coil → Main Load
Auxiliary contacts can provide feedback to the control system, while the Remaining LifeTime indication can support maintenance planning.
The contactor can be used alongside:
