6 / 10 page 6 Thermal (T- and TA-Line) TA45-2RU www.schurter.com /PG17_20 Circuit Breakers Effect of ambient temperature The units are calibrated for an ambient temperature of +23°C. To determine the rated cur- rent for a lower or higher ambient temperature, use a correction factor (typical value) from the table below: Ambient temperature [°C] Correction factor -10 0.89 -5 0.91 0 0.92 +23 1.00 +30 1.03 +40 1.08 +55 1.16 Example: Rated current = 5 A; Environmental temperature = 40 °C; --> Correction factor = 1.08; Resulting current = 5.5 A --> Fount to next higher rated current: 6 A Undervoltage release Max. operating voltage 1.1 Ue Rated operating voltage Ue 5 V 12 V 24 V 48 V 120 V 240 V 400 V 1) Current consumption (± 10%) 10.5 mA 16.5 mA 17.0 mA 3.2 mA 3.7 mA 3.1 mA 2.65 mA Highest reset level 0.85 Ue Lowest trip level 0.20 Ue Trip delay 20 ms - 50 ms Impulse withstand voltage (1.2 / 50 µs) ≥4 kV 1) only for 3pole Remote trip Permissible impuls duration of the make contact (no) Between terminal C and P1 unlimited Electrical load of the make contact (no) Current max. 12 mA / power max. 1.1 W Time-Current-Curves Type TA45 Rated current In <3 A 1 pole protected 2 pole protected Ambient temp. +23ºC 10'000 60 2`000 1`000 500 200 100 50 20 10 5 2 1 0,5 0,3 0,2 0,1 [ sec ] [ min ] 10 5 1 30 20 1,05 10 8 5 4 3 2 1,32 Multiple of Rated Current In Reference Temperature +23° 0,5 0,3 0,2 0,1 10'000 60 2`000 1`000 500 200 100 50 20 10 5 2 1 [ sec ] [ min ] 10 5 1 30 20 1,05 10 8 5 4 3 2 1,32 Type TA45 Rated current 3 A > In <18 A 1 pole protected 2 pole protected Ambient temp. +23ºC Multiple of Rated Current In Reference Temperature +23° |
