KTO 011: Thermostat (normally closed); contact breaker for regulating heaters. The contact opens when temperature is rising.

European Ratings

The typical European rating will distinguish between resistive and inductive load ratings. Below is an example of a typical European rating:
16(4)A 250V ~ T85 µ

In this example the 16 = resistive load amperage; (4) = inductive load amperage; A= amperage; 250V= voltage; ~ = AC; T85= Maximum operating temperature in centigrade; µ = micro-gap (<3mm) approved.

If there is less than 3mm of air space between a switch's contacts in the open position, a micro-gap approval (µ) may be granted. This mark indicates that the switch has general application approval with a qualifier that another device, such as a cord and plug, must provide an alternate means of disconnection from the main power source.
