The DOM11335SNI-B is a single-pole Domae miniature circuit breaker from Schneider Electric, rated 50 A with a C curve and a breaking capacity of 4.5 kA at 230/400 V AC per IEC 60898-1.
This part is classified as Obsolete by the manufacturer.
Key Ratings & Fit
The C-curve trip characteristic means it holds up to 5–10× rated current for short durations, suited for general-purpose distribution loads with moderate inrush — think lighting panels or mixed resistive-inductive circuits. The 4.5 kA breaking capacity at 230/400 V AC is the fault-clearing limit per IEC 60898-1; verify it coordinates with the upstream device's let-through energy in your selective coordination study. Single-pole (1P) construction protects one phase. The 18 mm width per pole is standard for DIN-rail MCBs, so it occupies one modular space in the enclosure. Operating temperature range is -25…60 °C, storage -40…70 °C.
Integration Notes
Strip length is 14 mm. The toggle actuator provides a visible contact-position indicator. IP20 finger-safe protection is standard for enclosed distribution boards. Compatible with comb busbars and distribution blocks for daisy-chaining multiple MCBs in the same panel.
