MP ci rcu it breaker
MasiBrpactTN circuit breaker is equipped
with true
two
step stored energy mechanism
which insures fast opening
and
closing
operations and compleiB sequence open
close-open without recharging mechanism.
MasiBrpactTN always has manual actuators :
charging handle, push to open and push to
close buttons. In addition, remoiB operation
is possible with field installable accessories:
•
the spring charging motor (MCH)
•
a closing release (XF)
•
an undervoltage trip device (MN) or shunt
trip (MX) for opening.
The manual operating mechanism
can
still
be used in an emergency. The addition of
the electrical operating mechanism does
not alter circuit breaker dimensions.
spring charging motor
(MCH)
Added to the manual operating mechanism,
a motor charges automatically the stored
energy mechanism (when the breaker
closes) making possible 0-C-0 cy cles
without recharging. Opening and closing
operations are instantaneous.
operation counter (COM)
With gear motor option only. The operation
couniBr is read from the front and gives the
total number of breaker operating cy cles.
"spring charged" switch
Type b switch, it is closed when spring is
charged.
It is delivered as standard with the spring
charging motor and has a common terminal
with it .
closing coil (XF)
This device releases the breaker closing
mechanism when the spring is charged.
The closing coil is rated for continuous duty.
The
closing release is supplied
on
request
and
can
be fitted even on manual operating
mechanism.
Anti-pumping function:
In case of permanently energized closing
coil (XF), the breaker remains in the open
position after it has been opened, either by
manual or electrical operation. The breaker
can be
re-closedonly if closing coil is
momentarily de�nergized.
note:
this anti-pumping function
can
be
disabled by series connecting a "ready to
close" switch (P F).
