Allen Bradley 156-C3P25NCD Solid State Contactor – 3-Phase, 25A, 600V AC, 5–32V DC Control Input, Zero-Cross Switching

The Allen Bradley 156-C3P25NCD is a robust 3-phase solid state contactor (SSC) designed for reliable, fast, and noise-free switching of AC loads in demanding industrial applications. Operating with a DC control voltage of 5–32V and supporting up to 25A at 600V AC, this contactor ensures efficient performance with minimal maintenance requirements thanks to its solid-state design.

Featuring zero-cross switching technology, the 156-C3P25NCD significantly reduces inrush currents and electrical interference, enhancing protection for both loads and upstream circuitry. Its open-type construction makes it suitable for panel mounting in custom assemblies, and its 3-phase capability makes it ideal for motor, heater, and industrial control applications requiring dependable, contactless power switching.
