DIN Rail Thermostat for Ventilation and Panel Cooling

Simple Thermostat Control for Cooling Fans and Ventilation

The Finder 7T.81 panel thermostat is a compact DIN rail thermostat designed to control fans, blowers, and ventilation equipment inside electrical panels and enclosures. This model is made for ventilation control, which means the contact closes when the panel temperature rises above the set temperature and opens again when the temperature falls below it.

It is an easy and effective way to automate enclosure cooling, helping reduce heat buildup and protect sensitive electrical components.

Compact DIN Rail Thermostat for Control Panels

With its slim 17.5mm width, this thermostat is a great fit for crowded control cabinets and electrical enclosures. It mounts on a standard 35mm DIN rail (EN 60715), making installation quick and straightforward for new builds or replacement jobs.

The compact housing, screw terminals, and long electrical life make it a practical choice for everyday panel cooling applications.

Ventilation Control That Works Automatically

This Finder thermostat is designed specifically for cooling and ventilation control. When the internal panel temperature exceeds the maximum set temperature, the contact closes to switch on a fan or other cooling device. Once the temperature drops back below the set point, the contact opens again.

That simple switching action makes it useful for keeping enclosures cooler without complicated programming or added control hardware.

Wide Temperature Control Range for Enclosures

The 7T.81.0.000.2301 version provides an adjustable temperature range of -20 to +40°C, making it suitable for many low- to moderate-temperature panel cooling applications. It uses a snap-action thermostatic bimetal sensor for dependable mechanical switching and a long service life.

• Temperature setting range: -20 to +40°C
• Switch differential: 7 K ±4 K
• Ambient temperature range: -45 to +80°C
• Protection rating: IP20

Easy Alternative to Complex Temperature Controllers

If you need a simple way to switch a cooling fan based on temperature, this DIN rail thermostat is a great alternative to more complex electronic controllers. It gives you direct temperature-based switching without programming, software, or extra setup.

That makes it a strong choice for users who want reliable panel cooling in a simple, compact format.
