The 5SL5206-7RC: The 10 kA breaking capacity at 440 V DC means it can safely interrupt a fault up to that level without cascading upstream — critical for DC bus protection in drives or solar combiner boxes. IP20 with conductors connected — fine inside an enclosure, not for wet areas.
Sourced to order against an RFQ through independent distribution. Availability and current pricing confirmed at quote time.
The depth is 76 mm, with an installation depth of 70 mm. Overall height is 90 mm, width is 36 mm (2 MW).
No — the 5SL4363-7 is a 3-pole AC breaker (54 mm wide, 3 MW) rated for 400 V AC, while this 2-pole DC breaker (36 mm wide, 2 MW) serves a different circuit. The footprint and terminal arrangement differ; a panel designed for the AC unit would need rework.
