100 amp circuit breaker 3 phase

A 100 amp 3-phase circuit breaker!

Here are some key details you might find useful:

Ratings:

• Amperage: 100 amps
• Voltage: 3-phase, typically 208Y/120V or 480V
• Frequency: 60 Hz (standard in North America)
• Frame size: Typically a 2-pole or 3-pole breaker, with a frame size of L or M (depending on the manufacturer and specific breaker model)

Breaker types:

• Molded case circuit breaker (MCCB): A common type of 3-phase breaker, designed for industrial and commercial applications.
• Air circuit breaker (ACB): A type of breaker that uses air as the arc-quenching medium, often used in industrial and commercial settings.
• Vacuum circuit breaker (VCB): A type of breaker that uses a vacuum as the arc-quenching medium, often used in high-voltage applications.

Applications:

• Industrial power distribution: 100 amp 3-phase circuit breakers are commonly used in industrial settings to distribute power to motors, lighting, and other equipment.
• Commercial power distribution: These breakers are also used in commercial buildings, such as offices, retail stores, and restaurants, to distribute power to lighting, HVAC, and other equipment.
• Data centers and server rooms: 100 amp 3-phase circuit breakers are often used in data centers and server rooms to provide power to high-density computing equipment.

Safety features:

• Overcurrent protection: The breaker will trip when the current exceeds the rated value (100 amps in this case).
• Short-circuit protection: The breaker will trip when a short circuit occurs.
• Ground fault protection: Some breakers may include ground fault protection, which detects and trips the breaker in the event of a ground fault.

Installation and maintenance:

• Installation: 100 amp 3-phase circuit breakers should be installed by a qualified electrician, following the manufacturer's instructions and local electrical codes.
• Maintenance: Regular maintenance is important to ensure the breaker operates properly. This may include checking the breaker's trip settings, cleaning the breaker's contacts, and replacing worn-out parts.
