1. Product Name
SIEMENS 3RT2625-1AL25 Contactor

2. Product Brief Introduction
The SIEMENS 3RT2625-1AL25 is a magnetic contactor from the Siemens SIRIUS 3RT series. Designed for robustness and reliability, it is an electromechanical switching device used for the remote control of three-phase power circuits, primarily for starting, stopping, and protecting electric motors and other industrial loads.

3. Product Description
The SIEMENS 3RT2625-1AL25 is a high-performance, three-pole magnetic contactor and a core component of Siemens' modular and globally recognized SIRIUS 3RT control system. Engineered for demanding industrial environments, its fundamental purpose is to safely and reliably make and break electrical connections under load. A quintessential and primary application is the control of three-phase electric motors, making it an indispensable component in systems involving a ‌SIEMENS MOTOR‌. The device operates on an electromagnetic principle: when its coil (rated according to the '-1AL25' suffix) is energized by a low-voltage control signal from a pushbutton, relay, or programmable logic controller (PLC), an electromagnetic field pulls in the armature, closing the main power contacts and supplying power to the load, such as a ‌SIEMENS MOTOR‌. De-energizing the coil opens the contacts, stopping the motor. It is built to withstand frequent operation and the high inrush currents characteristic of motor starts, featuring durable construction with silver-based contact materials for excellent arc quenching and a long electrical service life. A key advantage of this contactor, and the SIRIUS system as a whole, is its modularity. The 3RT2625-1AL25 can be easily fitted with a variety of snap-on accessories, including auxiliary contacts for control circuit signaling and feedback, mechanical interlocks for safety in reversing applications, and surge suppression modules for coil protection. This adaptability, combined with its reliable performance, makes it a fundamental, flexible, and widely used component in motor control centers (MCCs), industrial machinery panels, and various automation systems. It provides the critical switching function required for the dependable and safe operation of ‌SIEMENS MOTORs‌ in countless applications, from industrial pumps, fans, and compressors to conveyor systems and material handling equipment.
