Small Thermostat

KTO 011 / KTS 011

Small Thermostat

Thermostat (NC): Thermostat opens on temperature rise – for regulating heaters or for switching signal devices. Comes with red temperature dial.

Thermostat (NO): Thermostat closes on temperature rise – for regulating filter fans and heat exchangers or for switching signal devices. Comes with blue temperature dial.

Compact design
Wide adjustment range
Color coded temperature dials
DIN rail mountable

Switching difference	12.6 °F ± 7 °F tolerance (7 K ± 4 K)
Sensor element	thermostatic bimetal
Contact type	snap-action contact
Switching difference	12.6 °F ± 7 °F tolerance (7 K ± 4 K)
Max. switching capacity	15 A resistive / 2 A inductive @ AC 120 V 10 A resistive / 2 A inductive @ AC 250 V DC 30 W (DC 24-72 V)
Max. inrush current	AC 16 A for 10 sec.
Mounting	clip for 35 mm DIN rail, EN 60715
Dimensions	2.4 x 1.3 x 1.7” (60 x 33 x 43 mm)
Weight	approx. 1.4 oz. (40 g)

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.

Dual Thermostat

ZR 011

Dual Thermostat

The ZR 011 houses two separate thermostats, allowing the independent control of heating and cooling or other equipment.

Thermostat NC (normally closed): Thermostat opens at temperature rise – for regulating heaters or for switching signal devices. Comes with red temperature dial.

Thermostat NO (normally open): Thermostat closes at temperature rise – for regulating filter fans and heat exchangers or for switching signal devices. Comes with blue temperature dial.

NC / NO or NO / NO in one unit
Separate adjustable temperatures
Color coded temperature dials
DIN rail mountable

Part no.	Setting range		Setting range
01172.0-00	NC – open on rise	0 to +60 °C	NO – close on rise	0 to +60 °C
01172.0-01	NC – open on rise	+32 to +140 °F	NO – close on rise	+32 to +140 °F
01176.0-00¹	NO – close on rise	0 to +60 °C	NO – close on rise	0 to +60 °C
01176.0-01¹	NO – close on rise	+32 to +140 °F	NO – close on rise	+32 to +140 °F

¹ For regulating heat exchangers and fans (e. g. LE 019) and as an alarm contact for monitoring the interior temperature of electronic enclosures.
