As soon as a phase threshold is running, the instantaneous output associated with this threshold is activated. This output indicates that the protection element has detected a phase fault and that the time delay associated with the threshold has started.
Application
The TC-5231, TC-5232, and TC-5241 low temperature
thermostats are used to control temperature in air
conditioning or refrigeration systems. The low
temperature thermostat measures the coldest one-foot
section along the entire 20-foot sensing element.
The low temperature thermostats are applicable to
various applications such as: low temperature control
of steam coils; frost indication in storehouses or
orchards; temperature control of freezer cabinets,
display cases, beverage coolers, milk cooling tanks,
and air conditioners.
Features
• 20 ft. (6.1 m) element senses temperature over a
large area. Control responds to coldest one-foot
section of the sensor.
• Adjustable setpoint from 35 to 60°F (1.7 to 15.5°C)
with 5°F (3°C) fixed differential.
• SPDT and DPST versions.
• Rated for use at 17 full load amps (120/208/240
Vac), 24 non-inductive amps (120/208/240 Vac),
and 16 non-inductive amps (24 Vac). Capable of
controlling refrigeration equipment directly.
• UL and CSA approved.
• Capillary clips provided.
