Siemens SIRIUS 3RT1024-1AK60 Contactor Overview

The Siemens SIRIUS 3RT1024-1AK60 is a highly reliable and versatile contactor designed to handle moderate power loads within industrial environments. Engineered to operate with high precision, this contactor is part of the well-established SIRIUS product line, which is synonymous with robust construction and operational reliability.

Technical Specifications and Performance

Rated for AC-3 usage, this contactor can manage power circuits up to 5.5 kW at 400 V, which makes it a suitable option for a variety of applications, from motors to complex control systems. The contactor operates with a control voltage of AC 110V at 50Hz or 120V at 60Hz and is a 3-pole device, ensuring a wide range of operability and compatibility.

Constructed for durability, the SIRIUS 3RT1024-1AK60 is designed to perform up to 10 million mechanical operating cycles. With the addition of an auxiliary switch block, this robust performance remains unaffected, showcasing the device's commitment to longevity and stability in demanding industrial settings.

Main Circuit Characteristics

This contactor boasts three NO (Normally Open) contacts for main operations, with an impressive operational current capability. It can handle 40 A at AC-1 400 V in 40 °C ambient temperatures and maintains a 35 A rating at the same voltage in 60 °C environments. When operating at AC-3 400 V, it has a rated operational current of 12 A, and at AC-4 400 V, the rated current slightly increases to 12.5 A. This flexibility ensures that the contractor can adapt to various operational needs without compromising on efficiency or safety.

Ambient Conditions and Installation

The SIRIUS 3RT1024-1AK60 can operate in a wide range of ambient temperatures, from -25 °C to +60 °C, accommodating extreme conditions with ease. Its installation is suitable up to 2,000 meters above sea level, making it adaptable to various geographical locations.

With an IP20 protection class on the front, the device is well-guarded against solid objects and offers a pollution degree of 3, which indicates that it can withstand conductive pollution, or dry, non-conductive pollution that becomes conductive due to condensation.

Control and Auxiliary Circuits

In terms of control circuit performance, the SIRIUS 3RT1024-1AK60 exhibits excellent stability with an operating range factor of 0.8 to 1.1 for its magnet coil at both 50 Hz and 60 Hz. The inductive power factors for the pull-in and holding power of the coil are 0.76 and 0.28, respectively, ensuring effective energy use.

The contactor also boasts high contact reliability for its auxiliary contacts, with a failure rate of only one faulty switching per 100 million at 17 V and 1 mA, demonstrating Siemens' commitment to precision and quality.

Installation, Mounting, and Connection

Screw and snap-on mounting options provide flexibility during installation, with the ability to mount onto a 35 mm standard DIN rail. Dimensions are compact with a width of 45 mm, height of 85 mm, and depth of 91 mm, allowing for efficient space usage in electrical cabinets.

The electrical connection is designed with screw-type terminals for both the main and auxiliary circuits, with a variety of connectable conductor cross-sections, catering to solid and finely stranded wires, as well as accommodating different AWG cables.

Conclusion

The Siemens SIRIUS 3RT1024-1AK60 contactor is an exceptional component of any power management system, offering a blend of performance, resilience, and adaptability. Its specifications make it a prime choice for industries looking for a reliable solution to manage and switch moderate power loads within a wide range of operating conditions.
