Worldwide novelty ARMS
TM
– greater safety for maintenance personnel
If there is an accidental arc, the ARMS
TM s
ystem (Arcflash Reduction Maintenance System)
shuts down faster than a short circuit trip device. In connection with IZM, additional compo-
nents from the accidental arc protection system ARCON provide incremental protection
against accidental arcing.
With the new IZM series, Eaton presents a complete offering of air circuit-breakers (ACB)
up to 6300 A. Five construction sizes make it possible to select the most economical
switch for each project.
The new star is the circuit-breaker IZMX16. This innovative concept allows economical
construction of two circuit-breakers within a field width of 600 mm.
There is no greater performance within such small space.
Circuit-breakers IZM up to 6300 A
