2 TA3 Tripping characteristics [ min ] [ sec ] 1' 6 Type Rated current TA3 <3A (TC-1) 1, 2 pole [ min ] [ sec ] 1' 6 Type Rated current TA3 >3 2A (TC-1) (3 pole, max. 12A) 3 2 2` 1` 3 pole Ambient temp. +23 C 3 2 2` 1` 1,2,3 pole Ambient temp. +23 C ,, Tripping time,3,2,1 1, 1, Tripping time,3,2,1 1, 1, Multiple of rated current [ x In ] Multiple of rated current [ x In ] The above tripping characteristics apply to symmetrical overloads on all poles on the TA3 only. At asymmetric overloads on multi-pole types, the tripping characteristic will change. If a 2-pole type TA3 is loaded at one pole only, the tripping current will be shifted by factor 1. (TC-2). If a 3-pole type TA3 is loaded at one pole only, the tripping current will be shifted by factor 1.1 (TC-2). To meet the above tripping characteristic at asymmetric overloads on multi-pole types, the value of the rated current of the CBE has to be multiplied by the factor mentioned above. Effect of ambient temperature The unit is calibrated for an ambient temperature of +23 C. To determine the rated current for lower or higher ambient temperature, use a correction factor from the table below. Ambient Correction factor temperature [ C] 1-pole 2-pole 3-pole Example for 2-pole type: Rated current at +23 C. A Ambient temperature + C Correction factor 1. Chosen rated current at + C ambient temperature: A x 1. =.2 A
