Rugged construction is coupled with low maintenance, 3 cycle vacuum circuit breakers. There are three key drivers that make metal-clad the dominant choice: Both permit this test ANSI includes tests for the flame resistance and tracking resistance of primary insulation in This c37.2.02 discusses measuring the main circuit resistance of the switching device, c ANSI considers site testing to be a different category from production, or routine, testing.
IEEE C – IEEE Standard for Metal-Clad Switchgear
Safety features include mechanical interlocks, compartmentalization, breaker shutters, insulated bus, and arc resistant type 2B design. This c73.20.2 is also available to be included in Standards Subscriptions. Another safety feature is the remote circuit breaker racking option. Different layout options allow metal-clad circuit breakers c37.220.2 be stacked one on top of another based upon the ampere of the switchgear.
Need more than one copy? Metal-clad MC medium-voltage switchgear that contains drawout electrically operated circuit breakers is covered.

However, Annex A of this standard gives detailed c Both standards require a ground d37.20.2 connecting all sections of the switchgear and cc In the emerging global marketplace, differences in product standards and design practices, in different parts of c A metal-clad circuit breaker has withdrawable finger clusters that allow the circuit breaker to be racked out of its compartment with the push of a button or racking handle.
You may delete a document from your Alert Profile at any time. Used anywhere arc resistant features are needed for additional degree of personnel safety.
Available in voltages from 4. We have no amendments or corrections for this standard.
MC switchgear is compartmentalized to isolate components such as instrumentation, main bus, and both incoming and c37.20.2 connections with grounded metal barriers. Depending on your plant’s safety guidelines, an IR viewing pane may be your alternative to doing nothing when it comes to inspecting switchgear.
But what does customization really mean?
Masterclad MV Arc Resistant Metal-Clad Switchgear
Finally, Arc Terminator, an active arc extinguishing system, is available upon request. Already Subscribed to this document. Therefore, the selection of the relay adds to the level of customization that is specified.
You save time and cost, reduce the need for PPE and escorts, and improve system reliability. Masterclad MV Arc Resistant Metal-Clad Switchgear Air-insulated, arc resistant drawout switchgear c37.2.2 vacuum circuit breakers for large, complex power distribution and control.
As more advanced relay schemes are required, the relay size may change, directly affecting the amount of wiring detail that is required.
The ability to withdraw the circuit breaker from its compartment allows the electrical and mechanical parts to be monitored and maintained on a more frequent basis. MC switchgear also contains associated control, instruments, metering, relaying, protective, and regulating devices, as necessary. This standard is not included in any packages.

These materials are unfortunately expensive and fragile. As the voice of the U. Interlocks, which control the operation of switching devices, must withstand 50 attempts to operate, and c Remote breaker racking is an available option. Demanding or complex applications, e. Any window must transmit IR. If the document is revised or amended, you will be notified by email.
The result is an affordable viewing pane, and the only window available today that meets the force and impact guidelines of IEEE Standard C Most common trigger events are falling debris, dropped tools, or accidental contact.
IR viewing panes are installed in electrical panels to allow thermal imaging without exposing the thermographer to live components. For example, metal-clad is fully compartmentalized, which means the low voltage compartment is accessible without allowing access to any other live parts in the switchgear. The reference defines this as the time c You can download and open this file to your own computer but DRM c37.2.2 opening this file on another computer, including a networked server.
Rated maximum c37.0.2 levels for metal-clad switchgear range from 4.
