At asymmetricoverloads on multi-pole types, the tripping characteristicwill change. Ifa 2-pole typeT A35is loaded at onepole only ,the trippingcurr entwill be shiftedby factor 1.05 (TC-2). Ifa 3-pole type T A35 isloaded at one pole only,the tripping currentwill be shifted byfactor 1.10(TC-2). Tomeet the above tripping characteristic at asymmetricoverloads onmulti-pole types, the value ofthe ratedcurr ent of theCBE has to be multiplied bythe factor mentionedabove. effect of ambient temperature Theunit is calibrated foran ambient temperatur e of+23 C.T o determine the ratedcurr entfor lower orhigher ambient temperature, usea corr ection factor from the table below.
