Bolt on circuit breaker

A bolt-on circuit breaker is a type of circuit breaker that is designed to be installed directly onto a busbar or a cable, without the need for additional mounting hardware. This type of circuit breaker is typically used in industrial and commercial applications where space is limited and high fault currents are present.

Here are some key characteristics of bolt-on circuit breakers:

  1. Direct mounting: Bolt-on circuit breakers are designed to be mounted directly onto a busbar or a cable, eliminating the need for additional mounting hardware.
  2. High fault current rating: Bolt-on circuit breakers are designed to handle high fault currents, making them suitable for applications where high fault currents are present.
  3. Compact design: Bolt-on circuit breakers are designed to be compact and space-efficient, making them ideal for applications where space is limited.
  4. Easy installation: Bolt-on circuit breakers are designed to be easy to install, with a simple bolt-on design that eliminates the need for additional wiring or connections.
  5. High reliability: Bolt-on circuit breakers are designed to be highly reliable, with a low failure rate and a long lifespan.

Some common applications for bolt-on circuit breakers include:

  1. Industrial power distribution: Bolt-on circuit breakers are commonly used in industrial power distribution systems, where high fault currents and high power levels are present.
  2. Commercial power distribution: Bolt-on circuit breakers are also used in commercial power distribution systems, such as office buildings, shopping centers, and hospitals.
  3. Data centers: Bolt-on circuit breakers are used in data centers to provide high fault current ratings and compact designs that are suitable for high-density power distribution systems.
  4. Renewable energy systems: Bolt-on circuit breakers are used in renewable energy systems, such as wind farms and solar power systems, to provide high fault current ratings and compact designs that are suitable for outdoor applications.
