Siemens 3RT2024-2BB40-0CC0 Power Contactor, S0, 12A, 24V DC, Spring-Type, SIRIUS Original Brand New

Overview: Siemens SIRIUS 3RT2024-2BB40-0CC0 Power Contactor

The Siemens 3RT2024-2BB40-0CC0 is a high-performance SIRIUS 3RT2 series power contactor specifically designed for switching motors and general resistive loads in industrial automation and control systems. This 3-pole device features a compact Size S0 footprint while offering a robust current rating of 12 A (AC-3e/AC-3) and a power rating of 5.5 kW at 400 V.

A key feature is the 24 V DC coil voltage for efficient and reliable operation, coupled with advanced communication-capable functionality, allowing for seamless integration into modern, networked control architectures (via optional modules). The inclusion of spring-loaded terminals (also known as spring-type terminals) ensures fast, vibration-proof, and maintenance-free wiring, reducing installation time and increasing system reliability.
