It's the right curve when a standard B-curve would nuisance-trip on startup but a Z-curve would be too slow for short-circuit protection. Rated 480 VAC / 500 VDC, this breaker covers both AC distribution panels and DC control circuits — common in industrial panels where a single-pole device protects a 24 VDC solenoid bank or a 48 VDC signal loop. The 500 VDC rating is notable: most single-pole MCBs top out at 250 VDC, so this one handles series-string solar or battery-bank circuits without needing two poles in series. Single-pole width (roughly 17.5 mm) means it fits tight panel layouts where every millimeter of rail space is on the critical path.
If you're planning a turnaround and this breaker is on the BOM, it lands before the window — no broker chase required.
Integration into the panel
DIN-rail mount, single-pole width. Wire termination accepts up to 25 mm² conductor — enough for the 2 A load plus any daisy-chained feed-through. The comb-bus bar slot is standard for the S200 series, so grouping multiple poles on a shared incoming feed is a clip-in operation.
