Why Choose the Finder 7T.81.0.000.2402 Panel Thermostat?
The Finder 7T.81.0.000.2402 is a compact and reliable DIN rail-mounted panel thermostat designed for automatic temperature regulation and heating control within electrical enclosures, industrial control panels and automation cabinets. As part of the established Finder 7T Series, this mechanical thermostat provides dependable temperature-sensitive switching to help protect electrical equipment against low temperatures and condensation-related problems.
Featuring a normally closed (NC) contact and an adjustable temperature setting range of -20 to +60 °C, the Finder 7T.81.0.000.2402 automatically activates connected heating equipment when the enclosure temperature falls below the selected setting. Its snap-action bimetallic sensing mechanism provides reliable switching without requiring an external power supply for the thermostat itself.
With a 10 A rated switching current, 250 V AC contact rating and a slim 17.5 mm housing width, this thermostat is particularly suitable for industrial electrical cabinets where installation space is limited. Its standard 35 mm DIN rail mounting and straightforward screw-terminal connections simplify installation and maintenance.

Reliable Temperature Control for Electrical Enclosures
The Finder 7T.81.0.000.2402 enclosure thermostat regulates heating equipment using a temperature-sensitive normally closed contact. When the temperature inside an electrical cabinet falls below the selected setpoint, the thermostat contact closes to activate a connected heater. As the enclosure temperature rises above the switching threshold, the contact opens to interrupt the heating circuit.
This automatic switching process helps maintain suitable operating conditions for electrical and electronic components, particularly in installations exposed to low ambient temperatures or fluctuating environmental conditions. When used with an appropriately sized enclosure heater, the thermostat can help minimise condensation by maintaining the cabinet temperature above critical levels.
Unlike electronic temperature controllers, the Finder 7T.81.0.000.2402 uses a mechanical bimetallic sensing element and therefore requires no separate supply voltage for temperature measurement or switching. Its simple operating principle, robust contact construction and adjustable temperature dial make it a practical solution for industrial panel builders, maintenance engineers and automation specialists.

Frequently Asked Questions
What is the Finder 7T.81.0.000.2402 used for?
The Finder 7T.81.0.000.2402 is a mechanical panel thermostat used to control electrical enclosure heaters automatically. It helps maintain suitable cabinet temperatures and reduce condensation risks in industrial electrical panels and automation enclosures.
What is the temperature adjustment range of this thermostat?
The thermostat has an adjustable temperature setting range of -20 to +60 °C, allowing the heating activation temperature to be selected according to the requirements of the electrical enclosure.
Does the Finder 7T.81.0.000.2402 have a normally open or normally closed contact?
This model features a single normally closed (NC) contact. The contact closes when the temperature falls below the selected setting to activate a connected heater and opens when the temperature rises above the switching threshold.
What is the maximum switching current of the thermostat?
The Finder 7T.81.0.000.2402 has a 10 A rated contact current and a 250 V AC rated contact voltage. The permissible connected load depends on the electrical load category and the manufacturer's switching specifications.
Does this thermostat require an external power supply?
No. The thermostat uses a mechanical bimetallic temperature sensor and does not require an auxiliary power supply to operate. The connected heating circuit must still be supplied with the appropriate electrical voltage.
How is the Finder 7T.81.0.000.2402 installed?
The thermostat is designed for installation on a standard 35 mm DIN rail inside an electrical control cabinet or enclosure. Its compact 17.5 mm-wide housing and screw-terminal connections make it suitable for industrial panel installations.
