Allen Bradley 156-C3P30NCD Solid State Contactor – 3-Phase, 30A, 600V AC, 5–32V DC Control Input, Zero-Cross Switching

The Allen Bradley 156-C3P30NCD is a robust 3-phase solid state contactor (SSC) designed for efficient, contactless switching of AC loads in industrial environments. Rated for 30A at 600V AC and controlled via a 5–32V DC input signal, this device provides reliable, maintenance-free operation for high-frequency or vibration-prone applications where mechanical contactors are less suitable.

Featuring zero-cross switching technology, the 156-C3P30NCD reduces inrush current and electrical noise, protecting sensitive equipment and enhancing overall circuit longevity. Its open-type construction allows for flexible panel mounting in custom assemblies and makes it ideal for motor, heating, and automation control systems that demand fast, quiet, and durable solid-state performance.
