Installation in switchgearCurrent-carrying capacity in switchgearAs an example, the following table shows the continuouscurrent carrying capacity for circuit-breakers installed in aswitchgear with the dimensions indicated below.These values refer to withdrawable version circuit-breakerinstalled in non-segregated switchgear with a degree ofprotection up to IP31, and the following dimensions:2300x800x900 (HxLxD) for E1 - E2 - E3;2300x1400x1500 (HxLxD) for E4 - E6.The values refer to a maximum temperature at the terminals of120°C.For withdrawable circuit-breakers with a rated current of 6300A,the use of vertical rear terminals is recommended.Note:The tables should be used solely as ageneral guideline for selecting products.Due to the extensive variety of switchgearconstruction shapes and conditions thatcan affect the behavior of the apparatus,the solution used must always be verified.3Vertical terminalsHorizontal and front terminalsType Continuous capacity Busbars section Continuous capacity Busbars section[A] [mm 2 ] [A] [mm 2 ]35°C 45°C 55°C 35°C 45°C 55°CE1B/N 08 800 800 800 1x(60x10) 800 800 800 1x(60x10)E1B/N 10 1000 1000 1000 1x(80x10) 1000 1000 1000 2x(60x8)E1B/N 12 1250 1250 1250 1x(80x10) 1250 1250 1200 2x(60x8)E1B/N 16 1600 1600 1500 2x(60x10) 1550 1450 1350 2x(60x10)E2S 08 800 800 800 1x(60x10) 800 800 800 1x(60x10)E2N/S 10 1000 1000 1000 1x(60x10) 1000 1000 1000 1x(60x10)E2N/S 12 1250 1250 1250 1x(60x10) 1250 1250 1250 1x(60x10)E2B/N/S 16 1600 1600 1600 2x(60x10) 1600 1600 1530 2x(60x10)E2B/N/S 20 2000 2000 1800 3x(60x10) 2000 2000 1750 3x(60x10)E2L 12 1250 1250 1250 1x(60x10) 1250 1250 1250 1x(60x10)E2L 16 1600 1600 1500 2x(60x10) 1600 1500 1400 2x(60x10)E3H/V 08 800 800 800 1x(60x10) 800 800 800 1x(60x10)E3S/H 10 1000 1000 1000 1x(60x10) 1000 1000 1000 1x(60x10)E3S/H/V 12 1250 1250 1250 1x(60x10) 1250 1250 1250 1x(60x10)E3S/H/V 16 1600 1600 1600 1x(100x10) 1600 1600 1600 1x(100x10)E3S/H/V 20 2000 2000 2000 2x(100x10) 2000 2000 2000 2x(100x10)E3N/S/H/V 25 2500 2500 2500 2x(100x10) 2500 2450 2400 2x(100x10)E3N/S/H/V 32 3200 3100 2800 3x(100x10) 3000 2880 2650 3x(100x10)E3L 20 2000 2000 2000 2x(100x10) 2000 2000 1970 2x(100x10)E3L 25 2500 2390 2250 2x(100x10) 2375 2270 2100 2x(100x10)E4H/V 32 3200 3200 3200 3x(100x10) 3200 3150 3000 3x(100x10)E4S/H/V 40 4000 3980 3500 4x(100x10) 3600 3510 3150 6x(60x10)E6V 32 3200 3200 3200 3x(100x10) 3200 3200 3200 3x(100x10)E6H/V 40 4000 4000 4000 4x(100x10) 4000 4000 4000 4x(100x10)E6H/V 50 5000 4850 4600 6x(100x10) 4850 4510 4250 6x(100x10)E6H/V 63 6000 5700 5250 7x(100x10) - - - -3/6ABB SACE
