The shunt circuit between terminals 1 and 3 may be used for any signal that may be required in addition to the main circuit. However, since the circuit makes use of the bimetal strip as a current-carrying path, the trip time of the circuit protector may be slightly influenced. tiMe / cURRent cHaRacteRiSticS The standard characteristic is valid for an ambient temperature of 23C. However, if the device is to be used in an ambient temperature other than 23C, an allowance must be made when selecting the current rating. See the chart, graph and example below to help determine the right circuit protector rating for your application. aMbient teMpeRta URe coRRection factoR Ambient Temperature (C) - 20 - 5 0 + 10 + 20 + 30 + 40 + 50 + 60 Multiplication Factor 0.8 0.88 0.9 0.96 1 1.05 1.12 1.2 1.3 Example : Operating Characteristics : Normal Continuous Current = 1.8 A (min) 60 Ambient Temperature = 40C 30 20 Multiplication Factor = 1.12 (from graph) 10 5 Recommended Rating: 1.8 x 1.12 = 2.016 Select the Nearest Rating = 2 amps 1 (S) 50 20 10 5 2 1 0.5 0.2 0.1 1.05 1.32 2 3 4 5 8 10 Multiple of Current Rating (x I ) n Rated Current < 6A 6A Ambient 23C Temperature
