The Siemens SIRIUS series 3RT2024-1KB40 contactor serves as a critical component in control systems. It is rated for an operational current of 12 A, making it efficient for various industrial tasks. The contactor is designed to handle operational power up to 5.5 kW at 400 volts AC.

This unit operates on a coil voltage of 24 V DC, ensuring compatibility with a range of automation systems. The control voltage can vary from 0.7 to 1.25 times the specified voltage, allowing for flexibility in installations. With three poles, the contactor is structured to facilitate reliable switching processes.

An essential feature of the 3RT2024-1KB40 is its integrated surge suppression mechanism. This is achieved through a plugged-in varistor, which offers protection against overvoltage conditions. The contactor includes auxiliary contacts, incorporating one Normally Open (NO) and one Normally Closed (NC) configuration, providing variety in control scenarios.

It employs screw terminals for secure wiring connections. However, it cannot be expanded with additional auxiliary switches, making it a fixed configuration unit. Designed for operation in environments ranging from -25°C to +60°C, this contactor has an IP20 protection rating against solid objects. In terms of durability, it boasts a mechanical lifespan rated for up to 10 million operating cycles, reflecting its robustness and reliability for sustained use.
