Overview
The Square D 9001KP1 pilot light transformer is a compact, 30mm standard round indicator designed for industrial control panels and signaling applications. Part of Schneider Electric’s Harmony 9001K series, this unit combines a chromium-plated metal bezel with a green lens to provide clear visual feedback in manufacturing, process control, and automation systems. The integrated transformer block supports 110/120VAC input at 50/60Hz frequencies.
Key Features
- 30mm diameter form factor fits standard panel cutouts
- Chromium-plated metal bezel for durability and corrosion resistance
- Integrated transformer block simplifies wiring and reduces component count
- Automatic self-grounding design requires minimal additional wiring
- IP66 rated—oil-tight, dust-tight, and water-tight without protective boots
- Heavy-duty construction rated for harsh industrial environments
