WEG MPW40-3-U032 MAN.MTR PROTECTOR 25.0-32.0A MPW Starters

Protection of electric circuits + operation and protection of motors

The MPW Motor-protective Circuit-breakers are a compact solution for the protection of electric circuits, and operation and protection of motors up to 45kW (380V) or 55kW (440V). With high breaking capacity, thus allowing the installation in specific applications with high short-circuit current. They assure complete protection for electric circuits and motors through thermal and magnetic releases, where the thermal protection may be set to protect against overloads and is equipped with a differential mechanism with phase-loss sensitivity, and the magnetic protection is set at 13xIn for short-circuit protection.

There are two available models, ON-OFF through pushbuttons (MPW18) or through a handle (MPW40/80/100), and both models have trip indication, which allows the operator to visualize the status of the breaker. The starting handle can be locked with a padlock on "OFF" position, ensuring safety during maintenance.

• Magnetic - Through the magnetic release, the MPW series offer protection against short-circuit on installations and motors, with fixed setting of 13 times the maximum current on the setting range of the breaker.
• Thermal - The thermal release may be adjusted and is responsible for protecting against overload, and sensitivity against phase-failure of installations and motors according to IEC60947-4-1, trip class 10.
• The MPWs can be installed through direct mounting on DIN rail 35mm or with fixing screws through a PLMP adaptor (see accessories)
