Function

The Siemens 3RT2017-2BM41 serves as an electro-mechanical switch in control systems. Its primary function is to safely and remotely switch a 3-phase electrical motor or other high-power loads (up to 12 A / 5.5 kW) on and off. The 220 V DC control signal energizes the coil, closing the main power contacts and simultaneously changing the state of the 1 NO auxiliary contact for control circuit signaling.

Application

• Starting and stopping 3-phase AC motors (IE3/IE4 ready).
• Switching general resistive and inductive loads.
• Integration into control panels, HVAC systems, and machinery.
