All curves will only be maintained if the escutcheon is mounted on a vertical surface. Ambient temperature 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. F these applications we offer a mechanical pulse delay please enquire. Other characteristic curves upon request (e.g. pulse delayed, f high inrush currents capacitive loads). 4 www.e-t-a.de 708
