Applications
ETR202C and ETR202F
• Designed to provide air temperature
control and monitoring in switch
gear enclosures that are set up to
operate with heaters, fans, filter
ventilators, heat exchangers,
and/or signal transmitters.
• When the enclosure reaches the
pre-determined set point, tempera-
ture contacts in the thermostat are
activated and the fan or heater
automatically begins to operate.
• Thermostats prolong the life
expectancy of heaters and fans by
curtailing their operating hours and
also increase the working efficiency
of electrical components by expos-
ing them to fewer contaminants from
the surrounding environment.
ZR011
• The ZR011 houses two separate
thermostats, allowing the independent
control of heating and cooling or
other equipment. Both thermostats
offer wide adjustment ranges and
are color coded for easy function
recognition.
• Switching capacity:
NC: 10A resistive/2A inductive
@ 250 VAC
NO: 5A resistive/2A inductive
@ 250 VAC DC 30W
