Magnetic and Hydraulic-Magnetic Circuit Breaker 8340-F...
Description
Single and multipole magnetic circuit breakers with trip-free
mechanism and toggle actuation. A choice of fast magnetic only or
hydraulically delayed switching characteristics (S-type MO or HM
CBE to EN 60934) ensures suitability for a wide range of applications.
Industry standard dimensions and panel mounting. Options include
auxiliary changeover contacts. Low temperature sensitivity at rated
load.
Approved to CBE standard EN 60934 (IEC 60934).
Typical application
Control equipment, communications systems, transportation, power
supplies.

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).
