Siemens 3RT2038-1AK60 SIRIUS Power Contactor, 80A, S2, 1 NO+1 NC Original Brand New

Overview: Siemens SIRIUS 3RT2038-1AK60 Power Contactor

The Siemens 3RT2038-1AK60 is a high-performance, 3-pole power contactor from the globally recognized SIRIUS 3RT2 series. Specifically designed for safe and efficient switching of three-phase motors and resistive loads (AC-3e/AC-3), this device is a critical component in industrial automation and motor control applications.

Rated for a powerful 80 A (AC-3e/AC-3) and capable of switching motors up to 37 kW at 400 V, this Size S2 contactor is built for demanding environments. It features a versatile control coil operating on $110\text{V AC}$ at $50\text{Hz}$ or $120\text{V AC}$ at $60\text{Hz}$, and includes two integrated auxiliary contacts ($1\text{NO}+1\text{NC}$) for signaling and interlocking functions. The reliable screw terminals ensure a secure connection for the main and auxiliary circuits.

Key Benefits and Advantages

• High-Performance Motor Switching: Ideal for direct-on-line (DOL) starter applications, reliably switching motors up to $37\text{kW}$ (at $400\text{V}$) with an $80\text{A}$ rated operational current.
• Space-Saving SIRIUS Design: Part of the modular Siemens SIRIUS system, offering a compact Size S2 footprint for optimized control cabinet design and maximum flexibility.
• Integrated Auxiliary Contacts: Comes standard with $1\text{Normally Open}(\text{NO})$ and $1\text{Normally Closed}(\text{NC})$ auxiliary contact, simplifying wiring for control circuits and feedback.
• Global Versatility: Features a dual-frequency coil ($110\text{V AC}/50\text{Hz}$ and $120\text{V AC}/60\text{Hz}$), making it suitable for international use and ensuring easy spare parts inventory.
• Robust Connection: Utilizes proven screw terminal technology for secure and durable main and auxiliary circuit wiring, compliant with IEC standards.

Application

The 3RT2038-1AK60 is indispensable for reliable switching in:

• Industrial machinery and process control
