Why Choose the Finder 7T.81.0.000.2302 Panel Thermostat?
The Finder 7T.81.0.000.2302 is a compact, adjustable 10 A normally open (NO) panel thermostat designed for automatic temperature control in electrical enclosures, industrial control cabinets and switchgear assemblies. Part of the Finder 7T Series, this DIN rail-mounted thermostat provides reliable temperature-dependent switching for ventilation fans and cooling equipment, helping prevent excessive heat accumulation inside electrical panels.
Featuring an adjustable temperature range of −20 to +60 °C, the Finder 7T.81.0.000.2302 uses a snap-action bimetallic sensing element to monitor enclosure temperature without requiring an external operating power supply. Its single normally open (SPST-NO) contact closes when the temperature rises above the selected setting, activating connected cooling equipment. When the temperature falls sufficiently below the setpoint, the contact opens again.
With a 10 A contact rating at 250 V AC, compact 17.5 mm width, IP20 protection and convenient screw terminals, this thermostat is well suited to industrial electrical panels where dependable cooling control and straightforward installation are essential.
Key Advantages

Automatic Temperature Control for Electrical Panel Ventilation
Electrical enclosures can experience significant temperature increases due to heat generated by power supplies, contactors, variable frequency drives, transformers and other electrical components. Excessive internal temperatures can reduce equipment reliability, shorten component service life and increase the risk of unexpected system shutdowns. The Finder 7T.81.0.000.2302 helps manage these conditions by automatically controlling suitable ventilation equipment.
The thermostat operates through a bimetallic snap-action mechanism. When the enclosure temperature rises above the selected setting, its normally open contact closes, allowing a connected cooling fan or control circuit to operate. As the temperature decreases below the switching threshold, the contact reopens. The 7 ± 4 K differential helps prevent excessive switching around the selected temperature.
Its 17.5 mm DIN rail housing makes the Finder 7T.81.0.000.2302 especially useful in densely populated electrical panels. Because the thermostat does not require an auxiliary supply for its sensing mechanism, it offers a straightforward approach to automatic ventilation control, with screw terminals enabling convenient integration into new or existing electrical installations.
Typical Applications
- Automatic ventilation fan control in electrical cabinets.
- Industrial control panel temperature management.
- Switchgear and electrical distribution enclosures.
- PLC and industrial automation cabinets.
- Variable frequency drive and motor control panels.
- Machinery control enclosures.
- Industrial electronic equipment cabinets.
- Building automation and control installations.
- OEM electrical panel manufacturing.
- Temperature-controlled ventilation systems.
