Siemens 3RT2023-2AL24-3MA0 SIRIUS Power Contactor, 9 A, 4 kW, 2NO+2NC, Spring-Loaded, Size S0 Original Brand New

Overview

The Siemens 3RT2023-2AL24-3MA0 is a high-performance power contactor from the trusted SIRIUS series. Engineered for reliable and efficient switching of motors and other resistive loads, this S0 size contactor is a compact yet powerful solution for industrial control applications. Its robust design and high-quality components ensure long-term durability and operational safety.

Key Features & Benefit

• High Performance: Rated for 9 A and 4 kW at 400 V AC, making it suitable for a wide range of motor control applications (AC-3e/AC-3).
• Space-Saving Design: The compact S0 size allows for efficient use of panel space, simplifying installation in crowded enclosures.
• Reliable Connections: Spring-loaded terminals provide fast, vibration-proof, and maintenance-free connections, reducing installation time and ensuring a secure electrical contact.
• Integrated Auxiliary Contacts: Features a built-in 2 Normally Open (NO) and 2 Normally Closed (NC) auxiliary switch, offering a high degree of flexibility for signaling and control circuits. These contacts are captive, ensuring they remain a permanent part of the device.
• Safety and Durability: Built to Siemens’ rigorous quality standards, this contactor offers excellent electrical and mechanical life, reducing downtime and maintenance costs.
• Efficient Operation: The 230 V AC, 50/60 Hz coil provides reliable and energy-efficient operation

Function

The Siemens 3RT2023-2AL24-3MA0 functions as an electrically controlled switch used for switching a power circuit. When the 230 V AC coil is energized, it creates a magnetic field that pulls the main contacts together, allowing current to flow to the connected load. When the coil is de-energized, the contacts open, interrupting the circuit. The integrated auxiliary contacts (2 NO + 2 NC) can be used for feedback signals, interlocking circuits, or other control functions.
