200a circuit breaker

A 200A circuit breaker is a type of electrical breaker that is designed to interrupt an electrical circuit when the current flowing through it exceeds a certain threshold, typically 200 amperes.

Here are some key characteristics of a 200A circuit breaker:

1. Amperage rating: 200 amperes (A) is the maximum amount of current that the breaker is designed to handle.
2. Voltage rating: The breaker is typically rated for use with a specific voltage range, such as 120/240 volts AC.
3. Type: There are different types of circuit breakers, including:
   • Thermal-magnetic breakers: These breakers use a combination of thermal and magnetic elements to detect overcurrent conditions.
   • Electronic trip breakers: These breakers use electronic sensors to detect overcurrent conditions.
   • Molded case breakers: These breakers are designed for use in industrial and commercial applications and are typically larger and more robust than residential breakers.
4. Trip characteristics: The breaker may have different trip characteristics, such as:
   • Instant trip: The breaker trips immediately when the current exceeds the rated value.
   • Time-delay trip: The breaker trips after a short delay (typically 1-10 seconds) when the current exceeds the rated value.
   • Long-time delay trip: The breaker trips after a longer delay (typically 1-60 minutes) when the current exceeds the rated value.
5. Applications: 200A circuit breakers are commonly used in:
   • Residential and commercial electrical systems
   • Industrial power distribution systems
   • Data centers and telecommunications equipment
   • Medical equipment and hospital facilities
   • High-power applications, such as welding and manufacturing equipment

Some common uses for 200A circuit breakers include:

• Feeding a main electrical panel or subpanel
• Protecting a branch circuit or feeder circuit
• Providing overcurrent protection for a specific piece of equipment or load
• Meeting electrical code requirements for a specific application or location

It's important to note that the specific characteristics and applications of a 200A circuit breaker may vary depending on the manufacturer and the specific product. It's always important to consult the manufacturer's documentation and follow local electrical codes and regulations when selecting and installing a circuit breaker.
