Siemens 3RT2038-3XF44-0LA2 Traction Contactor 80A, 37kW, 110V DC Coil, S2 Frame Original Brand New

Overview

The Siemens 3RT2038-3XF44-0LA2 is a high-performance traction contactor engineered for demanding industrial applications. As part of the SIRIUS series, this robust 3-pole contactor is rated for AC-3e/AC-3 operation up to 80 A and 37 kW at 400 V. Designed with a solid-state operating mechanism and an integrated varistor, it ensures reliable and transient-free switching, protecting your connected equipment. The 110 V DC coil with a wide operating range (0.7-1.25* Uc) provides flexibility and stability in various power conditions. Its compact S2 frame size and removable auxiliary switch block make it a versatile and space-saving solution for control panels and automation systems.

Key Features & Benefit

• Exceptional Performance: Rated for 80 A and 37 kW (at 400 V), it handles high-power loads with ease, suitable for motor control, traction, and other heavy-duty applications.
• Integrated Protection: The built-in varistor provides surge suppression, protecting the contactor’s coil and surrounding circuitry from voltage spikes and transients, thereby extending the product’s lifespan.
• Reliable DC Operation: The 110 V DC solid-state operating mechanism ensures consistent and reliable performance, even with a wide voltage tolerance (0.7-1.25* Uc), ideal for applications with fluctuating power supplies.
• Versatile Auxiliary Contacts: Equipped with 2 NO + 2 NC auxiliary contacts, it offers excellent flexibility for signaling, interlocking, and control circuit integration.
• Dual Terminal Types: Features screw terminals for the main circuit for a secure, high-current connection, and convenient spring-loaded terminals for the control and auxiliary circuits, allowing for quick, tool-free wiring and reduced installation time.
• Modular and Removable: The S2 frame size is a space-efficient design, and the removable auxiliary switch block simplifies maintenance, configuration, and replacement, providing maximum flexibility in panel design.

Function

• Motor Control: Ideal for switching asynchronous motors and other loads in traction applications, conveyor systems, and industrial machinery.
• Power Switching: Used for switching high-current loads in various industrial and commercial settings.
• Control Circuit Integration: The auxiliary contacts enable complex control logic, such as interlocking with other devices, providing feedback to a PLC, or activating warning indicators.
