It delivers 10 kA and 15 kA breaking capacity, covering typical distribution board and motor branch-circuit fault levels.
Depth is 70 mm with a mounting depth of also 70 mm, so it sits flush with the rail. Height 121 mm. No back-of-panel clearance needed beyond the rail. IP20 with conductors connected; IP40 in the handle area. Sealable (padlockable) for lockout/tagout. Mounting position any, which simplifies layout.
The breaker is halogen-free, silicon-free, and sealable. IP20/IP40 rated. Degree of pollution 3, overvoltage category III. Specific RoHS/UL statements should be verified from the manufacturer's declaration.
