Common Questions
What size panel cutout do I need?
29.5mm long × 22.4mm wide — a rectangular cutout. The switch snaps in from the front and clips into place. This is a different size to the 40A KCD4 — check your measurements before cutting.
What's the difference between the 16A and 40A KCD4?
The 16A version is a 4-pin DPST suited to medium-draw equipment like compressors and standard welders. The 40A version is a 6-pin DPST designed for heavy-draw inverter welders and high-current machinery. Both have different panel cutout sizes.
Do I need to wire the lamp terminals on illuminated variants?
Only if you want the indicator to light up. Connect the lamp terminals to Active and Neutral. If you don't need the lamp, leave those pins unconnected — the switch will still function normally.
What terminals do I need?
6.3mm quick-connect insulated spade terminals rated for your current load. These are widely available at electrical wholesalers and tool shops.
