INTRODUCTION
The MD and ND Frame circuit breaker line includes types
MD6, MDX6, HMD6, HMXD6, CMD6, ND6, NXD6, HND6
HNXD6 and CND6 circuit breaker types; MD6 ETI, and CMD6
ETI motor circuit interrupters; types MXD6 and NXD6 molded
case switches. These devices are rated for operating voltages
up to 600 VAC, 50/60 Hz and 500 VDC.
INSTALLATION
MD and ND Frame devices are for use in individual
enclosures, panel boards, switchboards or other approved
equipment.
The installation procedure consists of inspecting, attaching
required accessories, mounting the device and connecting
and torquing the line and load wire connectors.
Mounting hardware and unmounted wire connectors (where
required) are available as separate catalog items.
Note: Trip unit and accessory installation should be
completed before the device is mounted and connected. (See
installation instructions supplied with trip unit and accessory
before proceeding).
Note: Motor circuit interrupters and molded case switches
are supplied as complete devices only.
Note: Molded case switches do not have a PUSH-TO-TRIP
button.
A. Turn off and lock out all power before installing or servicing.
B. Make sure that the device is suitable for the installation
by comparing nameplate ratings with system require-
ments. Inspect the device for completeness and check for
any damage before mounting.

MANUAL OPERATION
Manual operation of the device is controlled by the circuit
breaker handle and the PUSH-TO-TRIP button. The device
handle has three indicating positions, two of which are
molded into the handle to indicate ON and OFF. The third
position indicates a TRIP position and is between the ON
and OFF positions. (See Fig. 4)
A. Device Reset
After tripping, the device is reset by moving the device
handle to the reset position and then moving the handle
to the ON position.
NOTE: In the event of a thermal trip, the circuit breaker
cannot be reset until the thermal element cools.
B. PUSH-TO-TRIP Button
The PUSH-TO-TRIP button checks the tripping function
and is used to manually exercise the operating mechanism.
INSPECTION AND FIELD TESTING
MD and ND frame devices are designed to provide years of
maintenance free service. The following procedure outlines
how to inspect and test a circuit breaker in service.
Maintenance
Experience has shown that properly applied molded case
circuit breakers normally do not require maintenance. How-
ever, some industrial users may choose to establish an in-
spection and maintenance procedure to be carried out on a
regular basis. For detailed information, consult applicable
NEMA publications or your local Siemens sales office.
NOTE: Do not spray or allow any petroleum based chemi-
cals, solvents or paints to contact the molded parts
or nameplates.
3 Operación manual.
La operación de cierre y apertura del interruptor se efectúa por
medio de la manija y con el botón pulsador se logra un disparo de
prueba. La manija del interruptor tiene 3 posiciones, 2 de las
cuales están moldeadas dentro de la manija del interruptor e
indican “ON” conectado y “OFF”desconectado, la posición “trip”
disparo se encuentra entre la posición “ON” y “OFF” ver fig. 4.
A. Restablecer. Después de un disparo “tripping” el interruptor
debe ser restablecido, accionando la manija totalmente hacia abajo,
llevando después la manija hacia la posición de conectado “ON”.
Nota: En el caso de un disparo por sobrecarga (térmico) no podrá
serrestablecido, sino hasta que se enfríen los elementos térmicos.
B. Botón pulsador, para disparar púlsese el botón de disparo
“trip” para verificar la función de disparo y del mecanismo de
operación.
INSPECCIÓN
Consulte su oficina de ventas Siemens.
NOTA: No use aerosoles, ni permita que derivados químicos del
petróleo, solventes o pinturas, se pongan en contacto con las
conexiones eléctricas dentro o fuera del interruptor.
