4p connection busbar for SD1250 DC SE SSDDC4M1250 Systeme Electric

Connection busbar for SystemePact SP SD series switch-disconnectors for 1250 A, 4P; kit – 2 pcs. Connection busbars are used for series or parallel connection of 3-pole and 4-pole switches in DC networks to reduce operating costs. Series connection reduces the voltage at each pole, allowing for the interruption of large short-circuit currents. Parallel connection optimizes the use of devices according to the rated current.
