ML1H Temperature Switch
Brand: BarksdaleBarksdale's ML1H Temperature Switch provides high performance, quality reliability in a mechanical thermostat. The single set point ML1H and dual set point L2H, can switch, measure and control temperatures from -45° to 232° C (-50° to 450° F), 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 and L2H Series are electrically rated for 10 amps @ 125/250 Vac and 3 amps @ 480 Vac. Standard 3-& and 6-pin terminal strips simplify installation.
The ML1H and L2H Series are rated NEMA 4,13 with the optional NEMA 4X construction that 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 and CSA approved, ML1H and L2H Series Temperature Switches are perfect for your temperature sensing needs.
