Changeover breaker

A changeover breaker is a type of electrical breaker that is designed to switch between two or more circuits or sources of power. It is typically used in applications where it is necessary to switch between different power sources, such as between a main power source and a backup power source, or between different circuits or loads.

Changeover breakers are often used in critical applications such as:

  1. Data centers: To switch between primary and backup power sources to ensure continuous operation of critical systems.
  2. Hospitals: To switch between primary and backup power sources to ensure continuous operation of life-support systems.
  3. Industrial processes: To switch between different power sources or circuits to ensure continuous operation of critical equipment.
  4. Telecommunications: To switch between different power sources or circuits to ensure continuous operation of critical communication systems.

Changeover breakers typically have the following features:

  1. Multiple poles: Changeover breakers have multiple poles, each of which can be switched independently.
  2. Changeover mechanism: The breaker has a mechanism that allows it to switch between different poles or circuits.
  3. Interlocking: The breaker has interlocking mechanisms that prevent accidental switching or misoperation.
  4. Monitoring: The breaker may have monitoring capabilities to detect changes in the power source or circuit.

Types of changeover breakers:

  1. Manual changeover breakers: These breakers require manual operation to switch between different poles or circuits.
  2. Automatic changeover breakers: These breakers can switch between different poles or circuits automatically in response to changes in the power source or circuit.
  3. Soft-start changeover breakers: These breakers can switch between different poles or circuits while gradually ramping up or down the power to prevent sudden changes in the load.

Benefits of changeover breakers:

  1. Increased reliability: Changeover breakers can ensure continuous operation of critical systems by switching between different power sources or circuits.
  2. Improved safety: Changeover breakers can prevent accidental switching or misoperation, which can reduce the risk of electrical shock or other hazards.
  3. Flexibility: Changeover breakers can be used in a variety of applications and can be customized to meet specific requirements.
  4. Reduced downtime: Changeover breakers can minimize downtime by allowing for quick and easy switching between different power sources or circuits.
