General Electric TKUV9R 125A 2-Pole 480 V Circuit Breaker Potential Transformer

Meet the General Electric TKUV9R 125A 2-Pole 480 V Circuit Breaker Potential Transformer — a purpose-built solution that combines rugged overcurrent protection with built-in voltage sensing for streamlined control and metering. With a 125 A rating and 480 V capability in a two-pole design, this GE circuit breaker is engineered to support demanding industrial power distribution while simplifying relay and metering connections.

Key specifications

• Current rating: 125 A
• Poles: 2
• Voltage rating: 480 V
• Part Number: TKUV9R

Why this design stands out

The TKUV9R integrates a potential transformer directly into the breaker, enabling immediate voltage sensing for protection relays and metering without the need for separate PT wiring. This design reduces installation time, minimizes wiring complexity, and helps maintain clean, reliable signals for monitoring systems in 480 V environments. In busy electrical rooms, fewer connection points mean less potential for miswiring and quicker troubleshooting when issues arise.

Ideal use cases

• Industrial facilities with 480 V distribution networks seeking reliable protection and simplified sensing for relays and meters
• Panel retrofits or upgrades where space and wiring efficiency are priorities
• Applications requiring coordinated protection and voltage sensing from a single, compact device
• Electrical installations in manufacturing, data centers, and large commercial facilities that rely on precise monitoring of circuit conditions

Practical considerations

When selecting the TKUV9R, ensure compatibility with existing GE switchgear and the target 480 V distribution scheme. Installation should be conducted by a qualified electrician in accordance with local electrical codes and manufacturer guidelines. The integrated PT simplifies wiring logistics for protection relays and metering, but proper routing and secure terminations remain essential for optimal performance and safety.

What you gain

With the General Electric TKUV9R, you get dependable circuit protection together with direct voltage sensing — reducing wiring effort, enabling quicker system diagnosis, and supporting more efficient protection coordination in 480 V installations. If you’re looking for a two-pole solution that doesn’t compromise on sensing capability, this 125 A, 480 V breaker is a practical, proven choice for demanding industrial environments.
