The electromechanical hygrostat MRF012 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 is effectively prevented. Switch difference: 4% RH (3% tolerance) Permissible velocity: 15m/sec Contact type: change-over contact Contact resistance: 100,000 cycles Min. switching capacity: 20V AC / for DC 100 mA Max. switching capacity: 250 VAC, 5 (1) A for DC 20W EMC: acc. to EN 55014-1-2, EN 61000-3-2, EN 61000-3-3 Connection: 3-pole terminal for 2.5mm²; clamping torque 0.5Nm max.: rigid wire 2.5mm²; stranded wire (with wire end ferrule) 1.5mm² Mounting: clip for 35mm DIN rail, EN50022 Casing: plastic according to UL94 V-0, light grey Fitting position: variable Operating/Storage temperature: 0 to +60°C (+32 to +140°F) / -20 to +80°C (-4 to +176°F) Protection type: IP20 Note: Due to different production batches, there may be slight color difference or difference in the actual product, which will not affect the use.
