Welcome To G-TV! Today I will be showing you Pfannenberg’s FLZ520 series thermostats.
The SKT series is designed to provide air temperature control and monitoring inside
cabinets. It is housed in flame retardant plastic UL94VO, and has a thermostatic bimetal
sensor element. These heating and cooling devices come available in normally closed
and normally open modes of operation. The normally closed FLZ520 thermostats have a
red dial. They’re used with heaters and heater fans. The contact opens when rising
temperatures reach the set point, shutting the heater off. The normally open FLZ520 thermostats
have a blue dial, and are used for the control of cooling units or for switching signal transmitter
in the case of overheating. The contact closes when rising temperatures reaches a set point
temperature, turning the fan on. They can be din rail mounted, and have a 2 pole terminal
connection for 14 AWG wiring, with an operating voltage of 250 volts AC. The SKT series has
an adjustment range from 30 to 149 degrees Fahrenheit. Pfannenberg’s FLZ520 series
thermostats, along with thousands of other products and services are available at Galco.com
