Thermostats US-630AXOSR
Dimensional drawings
Specification Electrical rating :
125 VAC, 8A max., resistive load 250 VAC, 4A max., resistive load Operating temp. range : Products without thermal fuse One point fixed between 0 to 120°C Products with thermal fuse One point fixed between 0 to 90°C Differential : 8 to 15K Temp. tolerance : Operating temp. ±5°C / Returning temp. ±5°C Circuit resistance (initial value) : 70 m Ω or less (The value varies depending on the type of the thermal fuse and lenght of the lead wire) Insulation resistance : 100 M Ω or more (with a 500 VDC megger) Dielectric strength : 1,200 V / 1 minute Heat durability : 130°C / 24 hours (Except for the thermal fuse and the lead wire) Switching durability : 100,000 times or more (at rated load) *The differential varies slightly with the operating temperature. *Please contact us for the length of the lead wires, lead wires with Various terminals, and multiple types with two to six elements. *The operating temp. of Thermal fuse must be fixed higher 30°C against operating temperature of thermostat.

Contact type
O : Open on temperature rise O : Close on temperature rise
Contact material
O : Ag contact
*In case of the multiple element version, the model with the thermal fuse has higher selection priority if such model is available both with and without the thermal fuse.
