W A T L O W<strong>Heaters</strong>RAYMAX 1220and 2030Applications andTechnical DataSpecificationsWeight: Under 31.75 kg/m 2(6.5 lbs/ft 2 )Voltage and Wattage: Ratings arebased on the ceramic fiber heatermodule which is mounted in thecase. Up to 600VÅ(ac) ispossible.Terminals: Terminals are .25-20threaded studs. Two terminalsplus ground for single-phase, andthree terminals plus ground forthree-phase, are standard. Thesewill be located on the center lineof the length unless otherwisespecified. Terminals can belocated anywhere along lines Aand B (see illustration to the right),but not closer than 51 mm (2 in.)to the case ends.Mounting Legs: 25 mm (1 in.)standard; 76 mm (3 in.) optionalfrom stock. For made-to-orderunits, mounting legs can besupplied in any incremental lengthL from 13 mm (0.5 in.) to 76 mm(3 in.). No slots are provided inlegs less than 25 mm (1 in.) long.OptionsHeater Dimensions Min. Max.

The standard clamp canbe used with 3 mm (0.125 in.) O.D.sheath thermocouples. The standardclamp is 4.8 mm (0.1875 in.) high,but can be removed for flushmounting*.* 3 mm (0.125 in.) is standard. 4.8 mm(0.1875 in.) and 6 mm (0.25 in.) areavailable upon request.Several options are available withRAYMAX 1220 and 2030 models.From the following list, the first fourare illustrated on pages 292 to 293.Consult Watlow for more informationon any of the options.• Single-phase non-standardlocation power terminals• Terminal boxL22 mm (0.875 in.)38 mm(1.5 in.)30 mm (1.1875 in.)A B6 mm (0.25 in.)9 mm (0.375 in.)38 mm (1.5 in.)30 mm (1.1875 in.)The maximum re<strong>com</strong>mendedsurface temperature of the heater isbased on the rating of the ceramicfiber heater module. This can varyfrom 1095°C (2000°F) at lower wattdensities, to higher watt densities atreduced surface temperatures.
