Eaton BRN120AFC 120A 1-Pole 240 V Circuit Breaker Potential Transformer

Meet the Eaton BRN120AFC, a 120 A, 1-pole, 240 V circuit breaker designed for reliable protection of 240 V circuits in electrical panels. The model name BRN120AFC signals its place in Eaton’s BRN family and its potential-transformer capability, offering practical options for monitoring and control within protection schemes.

Designed for strength in demanding environments, this breaker delivers decisive interruption when faults occur on a single 240 V circuit. The 1-pole configuration is ideal for protecting individual feeders or dedicated loads, while the 120 A rating handles high-current circuits common in commercial and industrial settings. The integrated potential-transformer aspect broadens how you can integrate sensing and measurement into your protection strategy without swapping to separate devices.

• Current rating: 120 A
• Poles: 1
• Voltage rating: 240 V
• Part number: BRN120AFC
• Special feature: potential transformer capability integrated within the circuit breaker

Who this is for: electricians and electrical engineers designing or upgrading panels that require a reliable 120 A, 1-pole solution for 240 V circuits, with the option to leverage monitoring/sensing through the potential-transformer interface. It’s a practical choice when you need solid protection without expanding panel footprint.

Practical considerations: verify panel compatibility with BRN-series breakers and align installation with local electrical codes. During installation, follow standard safety practices and ensure the power is fully isolated. If you’re integrating with a monitoring system, the potential-transformer capability provides a convenient pathway for measurement and supervision without adding extra components.

In short, the Eaton BRN120AFC offers precise, dependable protection for high-current 240 V circuits in a compact, single-pole form factor, with the added flexibility of potential-transformer integration to support advanced monitoring scenarios.
