Current distribution Comb busbars for Declic and SFT residential devices

Transcription

1 Current distribution Comb busbars for Declic and SFT residential devices Comb busbar, for connecting 26 x 9 mm modules, consisting of two insulated bars to supply 1P + N devices (Declic, SFT, etc.). Due to the small amount of space occupied by the comb busbars, the connection terminals on devices are easy to access Bar clic Supply b by semi-rigid cable directly in the tunnel terminals of the device: v cross-section 16 for Declic v cross-section 10 for SFT b by semi-rigid cable via connector 14875: v cross-section 35 v cross-section v cross-section Electrical characteristics: b rated operating current: Ie (40 C): v 63 A with 1 central supply point v 90 A with 2 supply points b rated insulation voltage: 250 V b short-circuit withstand capacity: compatible with the breaking capacities of Merlin Gerin modular circuit breakers (1P + N).
