Curve F1 (instantaneous) for DC

Curve K1 (short delay) for DC

N.B. All curves will only be maintained if the escutcheon is mounted on a vertical surface.

Ambient temperature or mounting side-by-side does not influence the trip curve, derating is not required.

The breakers may trip in the event of current peaks < 0.003 sec. For these applications we

offer a mechanical pulse delay – please enquire.

Other characteristic curves upon request (e.g. pulse delayed, for high inrush currents or capacitive loads).
