ABB | T3N200TW | Circuit Breaker | 200A | 3-Pole | 600V | 25kA

Meet the ABB T3N200TW, a purpose-built 200A, 3-pole circuit breaker engineered for robust three-phase protection in commercial and industrial electrical systems. With a 600V rating and a 25kA interrupting capacity, it delivers dependable short-circuit interruption when it matters most, helping protect equipment, wiring, and personnel.

Key features

• Three-pole protection ensures simultaneous interruption across all phases for balanced and safer three-phase circuits.
• 200A continuous rating supports mid-to-high load circuits in panelboards and switchgear.
• 600V maximum operating voltage compatible with typical industrial power distributions.
• 25kA interrupting capacity provides a healthy margin against fault currents.
• Part number T3N200TW serves as the primary reference for compatibility during maintenance, retrofit, or replacement projects.

Specifications

• Amperage: 200A
• Poles: 3-Pole
• Voltage: 600V
• Interrupting Capacity: 25kA
• Applications: maintenance, retrofit, replacement

Ideal use cases

• Maintenance: safely protect and power down 3-phase circuits during service work in existing installations.
• Retrofit: upgrade or replace aging breakers in panelboards where a 3-pole, 200A, 600V device is required.
• Replacement: match your current system's protective device using the T3N200TW as the compatibility reference.

Compatibility and installation tips

Before ordering, verify fit and ratings in your equipment. The part number T3N200TW is the best reference for ensuring compatibility with your panel or switchgear. When replacing an existing breaker, compare mounting style, busbar connections, and any required trip characteristics with the existing unit to avoid mismatch.

Why ABB for this application?
