Siemens 3RT2038-1AH00 SIRIUS 3RT2 Power Contactor, 80A, 37kW, 48V AC Coil, Size S2 Original Brand New

Overview: Siemens 3RT2038-1AH00 Power Contactor

The Siemens 3RT2038-1AH00 is a high-performance, 3-pole power contactor from the SIRIUS 3RT2 family, designed for reliably switching electrical loads, particularly three-phase motors. With its compact design (Size S2), it offers excellent performance in a small footprint, making it a standard choice for machine building and industrial control panels.

This model is rated for up to 80 A (AC-3e/AC-3) and handles motor power up to 37 kW at 400 V. It features a robust 48 V AC, 50 Hz control coil and comes equipped with an integrated 1 Normally Open (NO) and 1 Normally Closed (NC) auxiliary contact for control and signaling purposes. All connections are secured via reliable screw terminals.

Key Benefit

• Space-Saving Design: The compact Size S2 dimensions are optimized for efficient cabinet mounting and density.
• High Switching Capacity: With an 80 A (AC-3) rating, it's perfect for demanding motor-switching applications up to 37 kW at 400 V.
• Integrated Auxiliary Contacts: The built-in 1 NO + 1 NC contacts simplify wiring and installation for interlocking and feedback circuits.
• Easy Installation: Screw terminals ensure a secure and durable electrical connection for the main and auxiliary circuits.
• Global Standard: As part of the SIRIUS family, it meets international standards (e.g., IEC, UL/CSA), ensuring compliance for worldwide use.

Application

The Siemens 3RT2038-1AH00 is typically used in industrial and commercial settings for:

• Motor Control: Direct on-line (DOL) starting and stopping of three-phase motors.
