SIVACON S8 Planning Principles – Circuit-breaker design
The cubicle dimensions are tailored to the circuit-breaker
sizes and can be selected according to the individual re-
quirements. The circuit-breaker design provides optimal
connect conditions for every nominal current range. In
addition to cable connections, the system also provides
design-verified connections to SIVACON 8PS busbar trunk-
ing systems.
The cubicles for 3W. and 3V. circuit-breakers ensure both
personal safety and long-term operational safety (Fig. 3/1).
The incoming, outgoing and coupling units in cir-
cuit-breaker design are equipped with 3W. air circuit-break-
ers (ACB) in withdrawable or fixed-mounted design or
alternatively with 3V. moulded-case circuit-breakers (MCCB)
(Tab. 3/1).
