Siemens 3RT2015-1AB02-1AA0 Power Contactor, 7A, 3kW, 24V AC, 1NC, S00 Original Brand New

Overview

The Siemens SIRIUS 3RT2015-1AB02-1AA0 Power Contactor is a high-performance, 3-pole switching device engineered for reliable motor control and load switching in industrial applications. As part of the modular SIRIUS 3RT20 series, this contactor provides exceptional switching capacity in a compact Size S00 form factor. Designed for seamless integration into modern control panels, it offers easy installation via screw terminals and is globally approved (IEC, UL/CSA).

Benefit

• Compact Design: The Size S00 minimizes panel space requirements, ideal for space-constrained installations.
• High Reliability: Part of the trusted Siemens SIRIUS modular system, ensuring long mechanical and electrical service life for demanding operations.
• Worldwide Usability: Approved for global standards, including IEC and UL/CSA, making it suitable for international machine building.
• Easy Wiring: Features secure screw terminals for main and auxiliary circuits, simplifying installation and maintenance.
• IE3/IE4 Ready: Optimized for use with modern, high-efficiency motors, supporting current and future energy standards.

Function & Application

The Siemens 3RT2015-1AB02-1AA0 serves as a core component in motor control circuits. Its primary function is the non-reversing switching of 3-phase AC loads, particularly:

• Switching Standard Motors: Direct On-Line (DOL) starting and stopping of motors up to 3kW at 400 V.
• Resistive Loads: Switching of heating elements or lighting circuits up to 18 A at 400V.
• Industrial Automation: Used in machinery, conveyor systems, pumps, fans, and general industrial control panels.
• Low Voltage Control: Controlled by a common 24 V AC control voltage, suitable for integration with PLCs and other low-voltage control systems.

Accessories and System Integration

This contactor is fully compatible with the comprehensive SIRIUS modular system accessories, including:

• Additional auxiliary switch blocks (front- and side-mounted)
• Thermal overload relays (for motor protection)
• Surge suppressors (for coil protection)
• Function modules (e.g., timing, interlocking)
