Breaker Position
Switch
A spring-loaded switch
is
used
for circuit breaker open/closed
position
input
to static
Trip lllc/cP/cPX trip units
The switch
assembly
is designed for simple
mounting
to
Type RL circuit
breakers, but can
be used for retrofit to other circuit
breakers
as well. The switch is wired to the
trip unit as a 52b contact
so
that an open connection
will
appear
as a closed breaker.

!nterposing
Relay
An interposing relay is required to
integrate
the Static
Trip lllC/
CP/CPX
model trip units' 1OOmA
12V
dc Output
1 signal
into
alarm or control schemes.
The interposing relay
provides
a 1A
12OY
acl125Y dc
normally open solid state contact
and can be
mounted in the circuit breaker compartment.

Potential
Transformers
Two
potential
transformer
models are
available
for use
with
power
metering
version
Static
Trip lll devices.
The catalog
number
PTN/-A is designed
for integral
mounting on
type
RL low voltage
power
circuit breakers;
the
PTM-B uses
a more
general purpose
mounting which
is
better
suited
for retrofit
applications.
Kits are available
which
include the
PT
module,
wire and
primary
fuse assemblies
for upgrading
Type RL,
circuit breakers
or
installation on other
manufacturers
equipment.
