Siemens SIRIUS 3RT2038-3AP00 Power Contactor 80A, 37kW, 230V AC with Spring-Loaded Terminal Original Brand New

Overview

The Siemens SIRIUS 3RT2038-3AP00 is a high-performance power contactor designed for reliable switching of motors and other electrical loads up to 80 A. Part of the renowned SIRIUS modular system, this size S2 contactor is engineered for demanding industrial applications. It features a robust 3-pole design suitable for AC-3e/AC-3 operation, handling up to 37 kW at 400 V. The 230 V AC, 50 Hz control voltage ensures compatibility with standard power systems.

A unique combination of screw terminals for the main circuit and innovative spring-loaded terminals for the control and auxiliary circuits simplifies wiring, reduces installation time, and enhances connection reliability. The integrated 1 NO + 1 NC auxiliary contact block provides flexibility for control and signaling functions.

Benefit

• High Performance & Durability: Engineered for AC-3e/AC-3 applications, this contactor offers long-term reliability and a long electrical service life, even under frequent switching cycles.
• Time-Saving Installation: The combination of traditional screw terminals for the high-current main circuit and spring-loaded terminals for the control circuit streamlines the wiring process, reducing labor costs and installation time.
• Enhanced Reliability: Spring-loaded terminals provide a vibration-proof, maintenance-free connection, ensuring stable operation in harsh industrial environments.
• Compact & Space-Efficient: As part of the SIRIUS modular system, its size S2 form factor is optimized for panel space, allowing for higher component density.
• Integrated Auxiliary Contacts: The built-in 1 NO + 1 NC auxiliary contacts eliminate the need for an external auxiliary block, saving space and simplifying the Bill of Materials (BOM).

Function

• Motor Switching: Efficiently and safely switches on and off electrical motors up to 37 kW.
• Load Control: Suitable for controlling resistive loads, lighting systems, and heating applications.
• Safety & Interlocking: The 1 NO + 1 NC auxiliary contacts can be used for safety interlocking, signaling, and control logic within a larger automation system.
• Automation Integration: Seamlessly integrates with other SIRIUS components like overload relays and circuit breakers to form a complete motor starter solution.
