Moeller B3.1 2-PKZ0 AC Magnetic Contactor

Moeller B3.1 2-PKZ0 AC Magnetic Contactor is an electromechanical switching device used to control AC power in industrial automation and motor-control circuits. In operation, an energizable coil creates a magnetic field that moves an armature to close or open a set of contacts, allowing control of connected loads such as motors, pumps, compressors, or conveyors from a control panel or automation system. The B3.1 2-PKZ0 designation identifies this specific model variant within the Moeller contactor family, providing the form-factor and mounting compatibility expected for panel installations. This contactor is commonly employed in start-stop control schemes and remote switching of higher-current AC loads in manufacturing, processing, and material-handling environments.
