Functionality

The Siemens 3RT2015-1MB42-0KT0 acts as a switch for electrical loads. When the 24V DC control voltage is applied to the coil, it energizes and closes the main contacts, allowing power to flow to the connected motor or load.

Simultaneously, the integrated 1 NC auxiliary contact opens, providing a clear indication of the contactor’s status to the control system. This functionality is crucial for safe and automated operation in industrial machinery, control panels, and automation systems.

Application

• Motor control for pumps, fans, and conveyor belts
• Switching of heating elements
• Lighting control systems
• General industrial automation and machinery
