1 Thermal Magnetic The breakers are availble as a complete entity or in kit form where a reaker rame and an interchangaeble trip unit are the basic components. The interchangeability feature covers the electromechanical trip units described here and the electronic devices described on page 2. ach Trip Unit is equipped with an Interchange Interlock that prevents the inadvertent use of a trip unit designed for the model in an 60 or vice versa. The standard lectromechanical are equipped with a patented fault type indicator. The device has two indicator flags, one indicating an overload event (coloured brown) and a second, coured blue, indicating a short circuit or an event triggered by an R. (If the indicated protection devices are present). Thermal protection devices are normally calibrated at an ambient temperature of degrees centigrade. Some executions are also available in a verison calibrated at 55 degrees. The time current curves published here are valid for both executions. The following versions are available: TM (line thermal magnetic protection) (...T sub type) trip unit designed for the protection of generic loads, the device is available as 3 and 4p model for the 60 and frame sizes. This sub type has an thermal and magnetic setting. The thermal setting range is 0.8 to x In and the magnetic relay is from 5- x In. (ixed at for Ratings < ). TM (Selective thermal magnetic protection) (...T sub type) trip unit designed for the selective protection of generic loads, it is available as 3 and 4p model for the 60 and, & breaker types. Making full use of the s unique propeties this device offers both full and enhanced selectivity with downstream devices as the Record Plus 60, the lfaplus, Red ine M's and the Surion Motor Starter. This sub type has an thermal and magnetic setting. The thermal setting range is 0.8 to x In and the magnetic relay is from 5- x In. TM (generator thermal magnetic) (...T sub type) Suitable for the protection of generator circuits and or long cable runs, the device is available as 3 and 4p model for the Standard (60 & ) and i-reak (60 & ) breaker types. This sub type has an thermal and magnetic setting. The thermal setting range is 0.8 to x In and the magnetic relay is from 3-5 x In. Mag reak (magnetic only) (...MO sub type) trip unit designed to offer short circuit protection for, use in motor protection circuits in coordination with a contactor and thermal overload relay in accordance with the standard. The device is available as 3 and 4p model for the 60 &, & breaker types This sub type has O thermal protection and an magnetic relay that is from to 5 x In. Y (non automatic - switch disconnector) 'dummy 'trip unit available in a 60 and variant. as no protection elements. esigned as switch disconnector..6
