Tripping characteristics
Eaton WMZT branch circuit breakers are available with “C” and
“D” tripping characteristics.
C-curve devices are suitable for application where medium levels
of inrush current are expected. Applications include small trans-
formers, lighting, pilot devices, control circuits, and coils. C-curve
devices provide a medium magnetic trip point.
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 WMZT 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.

Installation options
WMZT 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. WMZT circuit breakers can
also be reverse feed.
