These branch circuit breakers
are available in two terminal
configurations: standard box

terminals that accept multiple
conductors and ring-tongue
terminals, ideally suited to
demanding requirements of
the semi-conductor industry.
All breakers mount on
standard 35 mm DIN rail.
Bus connectors and feeder
terminal facilitate mounting
and wiring of multiple
miniature circuit breaker
arrays in control panel
assemblies. These circuit
breakers can also be
reverse feed.

●

Design according to IEC/EN 60947-5-1, IEC/EN 62019

●

Field installable

●

The specified minimum voltages are per contact—take into
account particularly in case of series connection

●

Self-cleaning contacts

●

Contact material and design particularly suitable for extra
low voltage

●

Z-NHK: the function of one of the two change-over
contacts can be switched from “auxiliary switch” to
“tripping signal switch”

●

Tripping signal contact transmits message of electric tripping,
not mechanical switch-off

●

Test key for contact function “electrical tripping”

●

Z-IHK-NA: will allow for > 480Y/277 Vac rating

UL 489 DIN Rail Miniature Circuit Breakers

Tripping Characteristics

D-curve devices are suitable
for applications where high
levels of inrush current are
expected. The high magnetic
trip point prevents nuisance
tripping in high inductive
applications such as motors,
transformers and power
supplies.

Eaton FAZ-NA and FAZ-NA-L
devices are current limiting,
which means they interrupt
fault currents within one half
cycle of the fault. Current
limiting devices offer superior
protection by reducing peak
let-through current and
energy.

UL 489 circuit breakers

Used for branch circuit protection, internal/external receptacles, external motors and HACR equipment
(heating, air conditioning and refrigeration).

UL 1077 supplementary protectors

Used for overcurrent protection within appliances or electrical equipment, where branch circuit protection
is already provided or not required.

Note: UL 489 devices can be used in place of UL 1077; UL 1077 devices cannot be used in place of UL 489.
