Single pole high performance versions of types 3300 and 3400 (section
2) thermal-magnetic circuit breakers with tease-free, trip-free, press-
to-reset, snap action mechanism (R-type TM CBE to EN 60934; M-type
with manual release -H). Available with fast acting and standard
magnetic tripping characteristics - types 433 and 434 - both with
threadneck panel mounting. Options include a separate shunt tap
terminal (-A3), and pull-to-trip manual release (-H).
Complies with CBE standard EN 60934 (IEC 934).
