The 15 kA rating under 60947-2 gives you headroom for industrial panel coordination where fault levels run higher than residential service. Operating frequency is 50 Hz only; this is not a 60 Hz part.
Depth is 70 mm, height 90 mm. Mounting position is any — vertical, horizontal, upside down — no derating needed for orientation. Supply can enter from top or bottom, which simplifies busbar routing in a crowded enclosure. IP20 rating applies only when installed in a distribution board with conductors connected — it's not a standalone outdoor device. The wide cold-end makes it viable for unheated utility rooms or outdoor-rated enclosures in northern climates.
