Masterpact MTZ Circuit Breaker Mounting Versions

Masterpact circuit breakers are available in fixed and drawout versions.

The drawout version is preferred in most applications due to its following benefits:

  • Visible separation of the power contacts by racking the device out.

  • Convenient and complete access to the device for periodic maintenance.

  • Easy device removal and replacement.
