What is interlocking of contactor?

Interlocking of a contactor refers to a safety mechanism that ensures two or more contactors cannot operate simultaneously when they control different parts of a system. This prevents potential damage or hazardous conditions by ensuring that conflicting operations are avoided. Interlocking can be achieved through electrical or mechanical means, ensuring that only one contactor can be energized at a time. This is commonly used in applications like motor control and safety circuits.
