S800 Busbar system
The S800 busbar system is comprised of:

S804-BBPC120 120 mm feed block, 4-pole
2
S804-BB250 250 A busbar, 4-pole and neutral with 24 contacts pins
S804-BB6 250 A busbar, 4-pole with 6 contacts pins
S803-BB250 250 A busbar, 3-pole with 24 terminal lugs and 2 end caps
S803-BBPC120 120 mm feed block, 3-pole
2
S800-BBIC Optional contact-protection cap for exposed terminal lugs
S800-END Optional end cap
The busbar, which can be shortened in length by the user, ensures the safe and rational

connection of the S800 high performance MCB. A cable cross-section of up to 120 mm
can be connected at the feed block.
