Product details

The 3-pole design protects three phases in a single housing, with a breaking capacity of 10 kA per EN 60898 and 20 kA per IEC 60947-2 — the higher IEC figure means it can handle fault currents up to 20 kA in industrial distribution panels where the standard allows it.

Ratings that matter for fit

Temperature derating is built into the spec: at 35 °C it holds the full 16 A, but at 60 °C it's down to 13.57 A, and at 75 °C it's 12.2 A (interpolated from the provided curve).

Installation depth is 70 mm; the overall depth is 76 mm, so allow that behind the panel door. Touch protection is built in — no exposed live parts after wiring.
