¹ When connecting with wires, wire end ferrules must be used.
Important note: The contact system of the regulator is subjected to environmental influences, thus the contact resistance may
change. This can lead to a voltage drop and/or self-heating of the contacts.
The mechanical thermostats KTO 011 and KTS 011 are two state regulators used to control heaters, coolers, filter
fans or signal devices.
KTO 011: Thermostat (NC); contact breaker for regulating heaters. The contact opens when tempe
rature is rising.
KTS 011: Thermostat (NO); contact maker for regulating of filter fans and heat exchangers or for swit
ching signal
devises when temperature limit has been exceeded. The contact closes when temperature is rising.
> Large setting range
> Small size
> Simple to mount
> High switching performance
