Thermostat NO+NC, Setting range: 0ºC to 60ºC
Thermostat NO+NC, Setting range: 0ºC to 60ºC
Catalog#: ETR203
This dual adjustable temperature thermostat, ETR203, for any enclosure, houses two independent thermostats, which reduces space requirements within the enclosure. One has a normally open (NO) contact, and one has a normally closed (NC) contact, which means that one thermostat's temperature setting could control cooling and the other thermostat could control heating. The devices controlled, such as a filter fan or a fan heater, will then turn on or off at the required temperature level, set by the user, which results in reduced operational cost.

Features
- Description: Device with two independent thermostats, unlike thermostats with changeover contacts, connected devices can be switched in different temperature ranges. One thermostat with a normally closed contact for regulating heaters, and one with a normally opened contact for regulating cooling devices or signal devices. Sensor element thermostatic bimetal. Mounting clip for 35 mm DIN rail (EN 60715).
- Material: Plastic according to UL94 V-0.
- Setting range: 0 °C to +60 °C. Switching temperature difference less than 7 °K, and switching point tolerance ±4 °K.
- Switch capacity: 240 V AC, 10(2) A. 120 V AC, 15(2) A. 24 V DC, 30 W. Value in brackets for inductive load.
- Operating temperature: -40 °C to +80 °C.
- Service life: > 100,000 cycles.
- Connection: Screw terminal for cable (0.5 to 2.5 mm²).
- Protection: IP 20.
- Approvals: CE, EAC, cULus_UL Listed.
- Finish: RAL 7035.
- Pack quantity: 1 piece.
- The dual thermostat can control two different devices where one requires a normally open (NO) contact and the other requires a normally closed (NC) contact
- Therefore, one thermostat allows energy to flow to a device when the set temperature has been exceeded (NO) and the other thermostat prevents energy to flow to a device when the set temperature has been exceeded (NC)
- Customers are able to adjust both thermostat's temperature settings (the dual thermostat can control two devices at a time)
- The installed devices, such as filter fans or fan heaters, automatically turn on or off when they are required, which reduces the operational cost of the control panel
- As two independent thermostats are housed together, one thermostat's temperature setting will control cooling and the other thermostat's temperature setting will control heating
- This thermostat will save space within the enclosure, when both cooling and heating devices have been installed, as only one device is required
- Customers can adjust the required temperatures, which means it can be installed in any enclosure
