L N L N 3LL2 STEGO - PRODUCT CATALOGUETECHNICAL DATA Switch difference¹ 4 % RH (±3 % tolerance) Permissible air velocity 15 m/sec. Contact type change-over contact Service life > 50,000 cycles Min. switching capacity AC 20 V / DC 100 mA Max. switching capacity AC 250 V, 5 A DC 20 W Connection 3-pole terminal for 2.5 mm², clamping torque 0.5 Nm max.: rigid wire 2.5 mm² (AWG 14) stranded wire² 1.5 mm² (AWG 16) Mounting clip for 35 mm DIN rail, EN 60715 Casing plastic according to UL94 V-0, light grey Dimensions 67 x 50 x 38 mm Weight approx. 60 g Fitting position variable Operating/Storage temperature 0 to +60 °C (+32 to +140 °F) / -40 to +60 °C (-40 to +140 °F) Operating/Storage humidity max. 95 % RH (non-condensing) Protection type IP20 Approvals UL File No. E164102, EAC, CQC ¹ at 50 % RH ² When connecting with stranded wires, wire end ferrules must be used. The electromechanical hygrostat is designed to control enclosure heaters so that the dew point is raised when a critical relative humidity of 65 % is exceeded. In this way condensation and corrosion in enclosures with electric/ electronic components is effectively prevented. > Adjustable relative humidity > Change-over contact > High switching capacity > Easily accessible terminals > Clip fixing Connection diagram Examples of connection Heater Hygrostat MFR 012 Hygrostat MFR 012 e.g. Filter fan Heater Filter fan, Cooling equipment, Signal device MECHANICAL HYGROSTAT MFR 012 Art.
