Eaton BRX2100 Thermal-magnetic circuit breaker - 65 kAIC
Part Number: BRX2100
Quick Summary
Engineered for robust protection, the Eaton BRX2100 thermal-magnetic circuit breaker delivers reliable overcurrent protection for BR-series panels and industrial control applications. This 100 A device operates at 120/240 V with a 50–60 Hz frequency and a 65 kAIC interrupt rating, delivering strong short-circuit resilience. A common challenge engineers face is nuisance tripping or compatibility gaps with existing panels; the BRX2100’s precise thermal-magnetic trip and BR main-circuit specification help mitigate that risk. UL Listed (E7819) and Federal Specifications (W-C375) certifications reinforce compliance in regulated facilities, while straightforward wiring with #14-2/0 AWG and compact dimensions simplify installation. The result is safer protection, reduced maintenance, and faster field replacements in distribution panels and control cabinets, supporting uptime and efficiency.

Thermal-magnetic operation combines overload protection with fast short-circuit interruption, reducing heat buildup and minimizing nuisance trips in demanding environments. This translates to improved equipment life and safer panel operation in manufacturing lines and distribution cabinets. Used in BR-series panels, it simplifies upgrade paths for legacy installations while preserving common wiring practices. The 100 A, two-pole design supports standard distribution setups at 120/240 V, enabling straightforward integration into existing control circuits and minimizing rewiring. Its 65 kAIC interrupt rating provides higher fault current handling, reducing downtime and extending service intervals in high-demand facilities. Wiring with #14-2/0 AWG simplifies field connections and speeds panel assembly, while compact dimensions help fit tight enclosures without sacrificing access for maintenance. Certifications and compliance accompany every unit, easing procurement and audit readiness. Finally, the UL Listed and Federal Specifications alignment offers a predictable performance envelope for regulated environments, reinforcing safety and reliability in automation projects.

FAQs
The BRX2100 is a two-pole BR-type breaker rated for 100 A and accepts #14-2/0 AWG wiring. Install per Eaton’s guidelines for BR panels, ensuring proper alignment of lugs, correct insertion, and adherence to enclosure clearance. This streamlined wiring pattern simplifies field installation while maintaining safe, code-compliant distribution protection.
The BRX2100 has a 65 kAIC interrupt rating, meaning it can safely interrupt fault currents up to 65,000 A at 120/240 V. This enhances fault clearance in high-current scenarios, reduces the risk of equipment damage, and supports reliability in moderately to heavily faulted electrical systems found in industrial environments.
Ideal for electrical distribution panels, control cabinets, and automation racks, the BRX2100 integrates seamlessly with BR-series breakers and standard BR panels. Its 100 A rating and 120/240 V operation make it suitable for shop floors, process lines, and machine control circuits where compact form and consistent protection are required.
The BRX2100 is UL Listed (E7819) and complies with Federal Specifications W-C375, ensuring alignment with safety and procurement standards. These certifications simplify audits, regulatory compliance, and customer acceptance in regulated industries such as manufacturing and distribution.
