SIEMENS 3RT2934-5AV61 Contactor

‌1. Product Name‌
SIEMENS 3RT2934-5AV61 Contactor

‌2. Product Brief Introduction‌
The SIEMENS 3RT2934-5AV61 is a magnetic contactor from the Siemens SIRIUS 3RT series. It is a robust and reliable electromechanical switching device designed specifically for the control and protection of three-phase electric motors and other high-power industrial loads.

‌3. Product Description‌
The SIEMENS 3RT2934-5AV61 is a high-performance, three-pole magnetic contactor, an integral component of the Siemens SIRIUS 3RT modular control system. Engineered for durability in demanding industrial environments, its primary function is to provide reliable, remote-controlled switching for three-phase power circuits. Its most critical application is the safe and efficient operation of electric motors, making it a key device for controlling a ‌SIEMENS MOTOR‌. The device operates on an electromagnetic principle: when its operating coil (specified by the '-5AV61' suffix) is energized by a low-voltage control signal from a source such as a push-button, relay, or programmable logic controller (PLC), the electromagnetic field pulls in the armature, closing the main power contacts. This action connects the three-phase power supply to the load, such as a ‌SIEMENS MOTOR‌, enabling its start. De-energizing the coil opens the contacts, safely stopping the motor. Built to withstand the rigors of frequent operation and the challenging high inrush currents of motor starts, it features a robust design with high-grade silver alloy contacts for effective arc quenching and an extended electrical service life. As part of the modular SIRIUS 3RT platform, the 3RT2934-5AV61 can be easily enhanced with various snap-on accessories, including auxiliary contact blocks for control signaling, mechanical interlocks for safety, and surge suppression modules. This flexibility makes it a fundamental, adaptable, and widely trusted component in motor control centers (MCCs), industrial machinery panels, and automation systems, providing the crucial on/off control for ‌SIEMENS MOTORs‌ in diverse applications, from pumps, fans, and compressors to conveyors and processing equipment.
