SIEMENS 3RT2516-2AP60 Contactor

‌1. Product Name‌
SIEMENS 3RT2516-2AP60 Contactor

‌2. Product Brief Introduction‌
The SIEMENS 3RT2516-2AP60 is a magnetic contactor from the Siemens SIRIUS 3RT product line. It is a robust electromechanical switch designed for the reliable remote control of three-phase electrical circuits, primarily used for starting, stopping, and protecting electric motors in various industrial applications.

‌3. Product Description‌
The SIEMENS 3RT2516-2AP60 is a high-performance, three-pole magnetic contactor, part of the widely trusted Siemens SIRIUS 3RT modular control system. Engineered for industrial durability, its core function is to act as a remotely operated power switch, safely making and breaking electrical connections in three-phase power circuits. A quintessential application is the control of electric motors, making it a vital component for operating a ‌SIEMENS MOTOR‌. When its electromagnetic coil (specified by the '-2AP60' suffix) receives a low-voltage control signal from a push-button, relay, or programmable logic controller (PLC), it activates, closing its main power contacts to supply energy to a connected load like a ‌SIEMENS MOTOR‌. De-energizing the coil opens the contacts, safely stopping the motor. Built to withstand the demanding conditions of frequent operation, it features a robust design with silver alloy contacts that provide excellent arc quenching and a long electrical service life, even under high inrush currents common during motor starts. A significant advantage of the SIRIUS system is its modularity. The 3RT2516-2AP60 can be easily enhanced with snap-on accessories such as auxiliary contact blocks for control circuit signaling and feedback, mechanical interlocks for safety in reversing applications, and surge suppression modules for coil protection. This versatility makes it a fundamental, flexible, and reliable component in motor control centers (MCCs), machinery panels, and automation systems, providing dependable on/off control for ‌SIEMENS MOTORs‌ in countless applications, including pumps, fans, compressors, and conveyors.
