Overview
The Square D 9001 KP38 is a compact 30 mm pilot light designed for control and signaling applications in industrial automation panels. This standard type (without lens) accepts interchangeable lens modules and offers universal voltage compatibility. Square D 9001 KP38 units are widely used in factory automation, machine tool panels, and electrical enclosures where cost-effective status indication is required. The modular design allows technicians to swap lens colors without replacing the entire assembly, simplifying maintenance and reducing inventory needs.
