ABB A2A200TT - 2A, 3-Pole, Circuit Breaker

ABB A2A200TT is a compact, dependable 2 A, 3-pole circuit breaker crafted for robust overcurrent protection in 3‑phase power systems. Designed to slot into panelboards, switchboards, and control panels, it delivers reliable interruption of fault currents with safe operation at the center of your electrical distribution.

• Current rating: 2 A
• Poles: 3‑Pole
• Breaker type: Circuit Breaker
• Configuration: 3‑phase protection for balanced trip across all phases
• Applications: ideal for industrial, commercial, and OEM environments requiring dependable protection in distribution panels and motor control centers

What makes the ABB A2A200TT stand out is its ability to synchronize protection across all three phases, simplifying installation in 3‑phase systems and reducing the risk of unbalanced faults. This 3‑pole design provides comprehensive coverage for motors, drives, and other 3‑phase loads, helping to minimize downtime and protect vital equipment.

Typical use scenarios include panelboards, switchboards, and control panels in harsh industrial environments, as well as OEM assemblies where compact, reliable overcurrent protection is essential. Pair the A2A200TT with compatible circuit protection strategies to achieve coordinated trip performance and safe disconnection of all live conductors during fault conditions.

In comparison to single‑pole solutions in a 3‑phase network, the 3‑pole configuration ensures all phases trip together, delivering consistent protection and simplifying maintenance planning. For engineers and technicians building or upgrading distribution systems, the ABB A2A200TT offers a precise, purpose‑built answer for 3‑phase protection needs.
