B-LINE ESTNC-F – Frequently Asked Questions
1) What does the Eaton B-Line ESTNC-F small thermostat actually do inside an electrical enclosure?
The ESTNC-F is a compact enclosure thermostat used to regulate the temperature inside an enclosure. It's the control side of a cooling setup, not the cooling itself, so it switches a filter fan or similar enclosure ventilation on and off as the internal air temperature moves. If you're specifying enclosure climate control, you order the thermostat plus the fan and exhaust grille separately.
2) Is this Eaton B-Line enclosure thermostat UL Listed for use in a control panel?
The ESTNC-F carries a UL Listing. That's the box most institutional and MRO spec sheets want ticked for a component going into a control enclosure, and it's the answer to give an inspector asking about the thermostat controlling your panel fan.
3) Will the ESTNC-F work with a NEMA 12 filter fan on my enclosure?
Yes. The ESTNC-F is catalogued with Eaton B-Line NEMA 12 filter fans, so it's the intended control for that style of dust-tight enclosure ventilation. The thermostat switches the fan; the NEMA 12 rating comes from the fan and grille assembly and the enclosure itself, not from the thermostat.
4) How much space do I need inside the panel to mount the ESTNC-F thermostat?
Plan for a footprint of 2.4 x 1.4 x 1.3 inches (height x width x length/depth). It's a small-body thermostat at just over a pound (1.12 lb), so it fits on a DIN rail area or free wall space in a panel where a full-size controller wouldn't. Leave clearance for air to circulate around the sensing body, otherwise the reading tracks the enclosure wall instead of the air.
5) Do I need a thermostat or a humidity control for a panel that's sweating?
Two different problems. The ESTNC-F is a temperature control, so it handles heat buildup from drives, transformers and power supplies by cycling a fan. Condensation in a cold or damp enclosure is a moisture problem, and that calls for a hygrostat or an enclosure heater instead. Panels in unconditioned outdoor or wash-down areas often get both: a thermostat for summer heat and a humidity control or heater for winter condensation.
6) What part number do I order for the Eaton B-Line small enclosure thermostat?
Order model ESTNC-F from Eaton B-Line. It's a single-model item, so there's no finish, voltage or setpoint suffix to pick on the order line.
