WEG MPW100-3-U090 Circuit Breaker, 690 VAC, 100 A, 50 kA Interrupt, 3-Pole, Thermal Magnetic Trip MPW100-3-U090

The MPW Series motor protective circuit breaker are a compact solution for the protection of electric circuits and operation and protection of motors up to 45 kW (380 V) or 55 kW (440 V). 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.
