It is rated 13 A at 230 V AC, 50/60 Hz, with a C-curve tripping characteristic (5–10× In, typical for motor and lighting loads with moderate inrush). The C-curve means the breaker holds through short-duration inrush up to about 10× rated current — good for small motors, pumps, and fluorescent lighting banks where a B-curve would nuisance-trip.
Dimensions, mounting, and panel fit
Width is 36 mm (2 modular units on a standard DIN rail), depth 76 mm, height 90 mm, with an installation depth of 70 mm. That 36 mm width means it occupies two adjacent 18 mm slots — check your panel layout if you are swapping from a single-pole breaker; you need the extra slot. Mounting position is any, which helps in tight enclosures where the rail is vertical or upside-down.
Temperature derating — what the ratings actually mean in a warm panel
At 40 °C it derates to 12.37 A, at 45 °C to 11.96 A, and at 55 °C to 11.36 A. Power loss per pole is 1.9 W at rated current in hot operating state; for a 2-pole device that is 3.8 W total dissipated inside the enclosure, so factor that into your thermal budget.
For BOM planning: this is not a phase-out or last-time-buy part.
