Siemens 3RT2934-5AR61 Magnetic Coil 400V AC, Compatible with 3RT2.3 Contactors Original Brand New

Overview

The Siemens 3RT2934-5AR61 Magnetic Coil is an essential spare part for maintaining the operational efficiency and reliability of your industrial control systems. Specifically designed for use with SIRIUS 3RT2.3 series power contactors (Size S2), this high-quality replacement coil ensures optimal performance under dual-frequency control voltages. Operating at a nominal control supply voltage of 400V AC at 50Hz or 400-440V AC at 60Hz, it is engineered to meet the demanding requirements of global industrial applications.

Key Benefit

• High Reliability: Ensures stable operation of Siemens 3RT2.3 contactors under varying electrical loads.

• Durable Construction: Designed to withstand industrial conditions for long-term use.

• Versatile Voltage Support: Compatible with 400 V AC at 50 Hz and 400-440 V at 60 Hz.

• Precision Control: Delivers consistent magnetic actuation for efficient circuit switching.

Function & Application

The Magnetic Coil 3RT2934-5AR61 is the core component of the contactor’s electromagnet system. When the specified control voltage (400V AC or 400-440V AC) is applied, the coil generates the magnetic field required to pull the armature and close the main contacts of the 3RT2.3 contactor. This action allows the contactor to switch motors, heating systems, lighting, or other high-current loads in various industrial and commercial settings. It is specifically a replacement coil for the contactors, not the complete contactor unit.
