200a 4 poles circuit breaker
A 200A 4-pole circuit breaker is a type of electrical breaker that is designed to protect a 4-wire electrical circuit from overcurrent and short-circuit conditions. Here are some key characteristics and applications of a 200A 4-pole circuit breaker:
Characteristics:
- Rated current: 200 amperes (A)
- Number of poles: 4 (four)
- Voltage rating: Typically 120/240 volts (V) or 208/240V
- Interrupting rating: Designed to interrupt currents up to 200A
- Trip characteristics: Typically has a thermal-magnetic trip mechanism, which means it trips when the current exceeds a certain threshold (usually around 150-180A) or when the temperature of the breaker exceeds a certain level
Applications:
- Residential and commercial electrical distribution systems
- Industrial power distribution systems
- Data centers and server rooms
- Healthcare facilities
- Educational institutions
- Government buildings
Common uses:
- Feeding a 4-wire electrical circuit, such as a 120/240V single-phase circuit or a 208/240V three-phase circuit
- Protecting a group of electrical devices, such as lighting, receptacles, and appliances
- Providing overcurrent protection for a specific area or zone of a building
- Meeting electrical code requirements, such as those set by the National Electric Code (NEC) or the International Electrotechnical Commission (IEC)
Types of 200A 4-pole circuit breakers:
- Molded case circuit breakers (MCCBs)
- Air circuit breakers (ACBs)
- Vacuum circuit breakers (VCBs)
- Arc-fault circuit breakers (AFCBs)
- Ground fault circuit breakers (GFCBs)
When selecting a 200A 4-pole circuit breaker, it's essential to consider factors such as the voltage rating, current rating, and trip characteristics to ensure that the breaker is suitable for the specific application and meets the relevant electrical codes and standards.
