Main Features

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 60cv (380V) or 75cv (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 release may be set to protect against overloads and is equipped with a differential mechanism with phase-loss sensitivity, and the magnetic release is set at 13xIn for short-circuit protection.

There are two available models, On-off through pushbuttons (MPW12/18) or through a handle (MPW40/65/100), 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.
