What Are Finder 7H Panel Heaters?

Electrical panels don’t like the cold. This is because low temperatures can lead to damp, and cause corrosion, short circuits and shutdowns. Enter the Finder 7H series: built to keep your control boxes warm, dry, and happy — even when the weather outside is doing its worst.

Why Use Panel Heaters?

Imagine your control panel is a luxury car. You wouldn’t leave it parked outside in the rain with the windows open, right? Don't leave your electronic enclosures exposed to the elements, either! Panel heaters maintain a consistent internal temperature, preventing condensation and protecting your components year-round — all while using energy-efficient, self-regulating technology.

What Makes Finder 7H Heaters So Smart?

  • Self-regulating heat control – They automatically adjust output depending on the ambient temperature. Too cold? They crank it up. Too warm? They dial it back. No wasted energy, no constant monitoring.
  • Power options from 25W to 400W – There’s a size to suit every setup, whether you're heating a small junction box or a full-sized panel.
  • Touch-safe design – Surface temperatures stay below 100°C, so you won’t accidentally brand yourself when checking your cabinet.
  • Multi-voltage support – Compatible with 110–230 V AC/DC systems.
  • Easy DIN rail mounting – Snaps right onto a standard 35 mm DIN rail.
