Integration context
The 3-pole construction handles three-phase circuits directly — no need to gang single-pole units. Terminal design accepts copper conductors up to 25 mm², which is adequate for the 8 A rating and the short-circuit duty. Panel builders should verify that the upstream protective device (fuse or MCCB) has a rated short-circuit capacity at least equal to the prospective fault level at the point of installation; the 15 kA Icu is the breaker's own withstand, not a coordination guarantee.
