Outstanding Design
WEG Manual Motor Protectors are the
state-of-the-art products available for
worldwide market. With the latest
technology and design, you’ll find how easy
is to save panel space and to face almost
any application in motor control. Built in a
very compact frame size, WEG’s Manual
Motor Protectors combine, added
information short-circuit and motor overload
protections in just one component.
These devices include a three-position
rotary ON-TRIP-OFF handle, which can be
padlocked in the OFF position.
WEG Manual Motor Protectors are
designed for DIN rail mounting, while lugs
for direct panel mounting are also available
as an accessory.
Even Better Performance
Motor protectors include some of the same
features you can find in WEG’s RW bimetal
overload relays, such as Class 10
protection, ambient temperature
compensation and phase failure sensitivity,
which give you all the protection your
motors need. For short circuit protection,
the magnetic device trips at 13 times the
maximum FLA of the component.
A product for the world
Motor protectors are designed for use
according to international standards, making
them suitable for applications all over the
world. Because of the multiple approvals
WEG’s Manual Motor Protectors can be
used for many different applications. IEC
standards recognize MPW series as a Circuit
Breaker. According to this, different functions
are available:
g
Motor Circuit Protection
g
Manual Disconnect
g
Main Switch
g
Emergency Disconnect
So, if you export your motor control panels
outside the U.S. and Canada, the MPW
series are your right choice. Also, UL508
has MPW series listed as Motor Controller,
allowing them to be used in several different
configurations:
g
Manual Motor Starter,
g
Combination Starter,
g
Group Motor Installations,
g
Motor Disconnect Applications
So, if you use your motor control panels
inside the U.S. and Canada, the MPW series
are still your right choice.
When using WEG’s contactors connected
with the MPW series, you can provide a
remote control either using pushbuttons or
any other remote control device. Manual
Motor Protectors can handle a wide range
of applications, not only three phase motor
control but single phase and DC motors as
well.
