Barksdale's ML1H & L2H Series Temperature Switches provide unmatched performance, quality & reliability in a mechanical thermostat. The single set point ML1H and dual set point L2H, can switch, measure & control temperatures from -50° to 450°F (-45° to 232°C), while the optional adjustable differential provides precise control. These locally mounted switches provide fast response and accurate measurements at the temperature source. Both the ML1H & L2H Series are electrically rated for 10 amps @ 125/250 VAC & 3 amps @ 480 VAC. Standard 3- & 6-pin terminal strips simplify installation. The ML1H & L2H Series are rated NEMA 4 & 13; the optional NEMA 4X construction protects the rugged die-cast aluminum enclosure from corrosive environments. Copper or stainless steel temperature sensors are available to handle a wide range of media. Optional thermowells allow the sensor to work in pressurized vessels to 5000 psi. UL listed & CSA approved, ML1H & L2H Series Temperature Switches are perfect for your temperature sensing needs.
