Control and Protection-Auxiliary Contact
KRIPAL offers a range of specialized accessories to extend the functionality and reliability of our contactors. Auxiliary contact blocks, available in NO/NC configurations with lower current ratings (typically up to 5A), are used for electrical interlocking, status indication, and control circuit logic. Mechanical interlocks provide a hardware-based safety mechanism to prevent simultaneous operation of two contactors, essential for applications like motor reversing.
