500kw mccb breaker

A 500kW MCCB (Molded Case Circuit Breaker) breaker is a high-power electrical device used to protect electrical circuits from overcurrents and short circuits. Here are some key characteristics and features of a 500kW MCCB breaker:

Ratings:

• Rated current: 500kW (or 500A)
• Rated voltage: typically 3.3kV to 36kV, depending on the manufacturer and application
• Rated breaking capacity: typically 100kA to 200kA, depending on the manufacturer and application

Features:

• High-speed tripping: MCCB breakers are designed to trip quickly (typically within 1-2 cycles) in the event of an overcurrent or short circuit, reducing the risk of damage to equipment and minimizing downtime.
• High-temperature withstand: MCCB breakers are designed to withstand high temperatures, making them suitable for use in high-temperature applications.
• Low-maintenance: MCCB breakers are designed to be easy to maintain and repair, with minimal components and no moving parts.
• High-reliability: MCCB breakers are designed to provide high reliability and uptime, with a low failure rate and minimal downtime.

Applications:

• Industrial power distribution systems
• Commercial power distribution systems
• High-power industrial processes (e.g. manufacturing, mining, oil and gas)
• High-power commercial applications (e.g. data centers, hospitals, shopping centers)

Types of 500kW MCCB breakers:

• Air-break MCCB breakers: These breakers use air as the arc-quenching medium and are suitable for use in dry, clean environments.
• Oil-break MCCB breakers: These breakers use oil as the arc-quenching medium and are suitable for use in harsh environments where air-break breakers may not be effective.
• Vacuum-break MCCB breakers: These breakers use a vacuum as the arc-quenching medium and are suitable for use in high-reliability applications where minimal maintenance is required.

Manufacturers:

• Some common manufacturers of 500kW MCCB breakers include:
  • ABB
  • Schneider Electric
  • Siemens
  • GE
  • Mitsubishi Electric

Cost:

• The cost of a 500kW MCCB breaker can vary depending on the manufacturer, type, and features. However, as a rough estimate, a 500kW MCCB breaker can cost anywhere from $5,000 to $20,000 or more, depending on the specific requirements of the application.
