wy TEXAS INSTRUMENTS KLIxoN Precision Thermostats 7BT2 Series High Capacity, Environmentally Sealed 1/2" Thermostat Features High Current Capacity Normally Open or Closed Pre-set, Non-adjustable Temperature Calibration UL Recognized, file #36418 CSA Recognized, file #LR24458 e VDE Recognized, tile #4464,4-451/A1 Overview Description The Klixon 7BT2 thermostat is a snap-acting disc type control designed to provide crisp, positive switching action. The bimetal disc and electrical contacts are enclosed in a stainless steel cup to provide protection from dust and other foreign particles. The 7BT2 is available in a variety of configura- tions, making it a versatile candidate for your thermal protection needs. MCSS007 Printed in U.S.A. 1/00 Switching Action All 7BT2 thermostats are supplied with single pole, single throw switching that can be constructed as either Open on Temperature Rise or Close on Temperature Rise. Temperature Ratings The standard operating temperatures, differentials and tolerances are shown in the table below, but can be customized to meet you specific requirements. Operating Temperature | Operating Temperature Differential Tolerance Range F Range C OF C OF 9 30.0 to 204.0 -i.1 to 95.6 20.0 11.1 5.0 2.8 205.0 to 304.0 96.1 to 151.1 30.0 16.7 8.0 44 305.0 to 400.0 151.7 to 204.4 40.0 22.2 12.0 6.7 The standard operating temperatures, differentials and tolerances are shown in the table below, but can be customized to meet you specific requirements. Ambient Temperature Range Operating Temperature Range -40F to +4640F (-409C to +2409C) +300F to +4000F, (-1.19C to +204.40C) Operating Temperature : Temperature at which normally closed contacts open or normally open contacts close. Differential: Subtract the differential from the nominal operating temperature to determine the temperature at which the contacts will return to the normal position (reset temperature).Wy TEXAS INSTRUMENTS Performance Characteristics Contact ratings (Amperes) - UL/CSA/VDE Ratings 120 VAC | 240VAC | Life Cycles Agence Max.
