Featuring 110 A rated amperage and a 65 kAIC interrupt capacity, the BRX2110 provides robust protection for branch circuits in industrial panels. Its two-pole design and 120/240 V operation suit motor starts and distribution blocks in manufacturing environments. The device is designed for BRX frame installations, enabling quick selection and consistent performance in control cabinets. Thermal-magnetic protection delivers fast, selective trips and reliable arc suppression in busy control cabinets. This design helps coordinate with motors and other loads to minimize downtime. The enhanced magnetic trip element improves high fault-current performance, reducing the risk of cascading trips in interconnected automation equipment. Wire compatibility supports #14-2/0 AWG conductors, simplifying field wiring and reducing the need for adapters. A compact 3 x 3 x 2 inch footprint fits standard panels without rework, while providing ample clearance for termination and labeling. This makes retrofit projects faster and less costly. UL Listed (E7819) and Federal Specifications W-C375 provide regulatory assurance for industrial controls and NEC compliance. The listing demonstrates traceability and quality control across Eaton's BR family. Built for 50-60 Hz operation, it performs predictably in global facilities and varying duty cycles. The BR main circuit breaker reference aligns with BRX series installations, enabling straightforward replacement and future expansion. Mounting is straightforward in standard enclosures, and the unit handles routine maintenance checks without special tools. Field technicians will appreciate the clear labeling and compatible wire ranges during commissioning. With 50-60 Hz operation and a weight around 0.5 lb, this unit supports reliable, vibration-tolerant performance across global facilities. Its rugged construction resists shock and ambient temperature variations typical of industrial environments. When combined with Eaton's warranty and support ecosystem, it reduces total cost of ownership by limiting unexpected trips and material waste.

FAQs
The BRX2110 is a two-pole device intended for installation in 120/240 V panels. Use compatible mounting on BRX frames and ensure conductor size meets torque specs for #14-2/0 AWG. Leave adequate clearance for heat dissipation and labeling; follow UL E7819 guidelines and local electrical codes during wiring and testing.
The 65 kAIC interrupt rating indicates the maximum fault current the breaker can interrupt without damage. At 110 A, it provides dependable protection against short-circuit events while preserving downstream devices. In practice, verify system fault levels and coordinate with upstream protection to minimize nuisance trips and ensure selective tripping.
Yes, BRX2110 is well suited for motor control centers and distribution blocks in manufacturing and process environments. Its 120/240 V two-pole configuration handles motor starting currents, while the 65 kAIC rating supports high fault current environments. Use it where space is tight and predictable, repeatable protection is required.
UL Listed E7819 and Federal Specifications W-C375 provide regulatory assurance and traceability. These certifications simplify audits, NEC/CSA alignment, and procurement with confidence that the device meets safety and performance standards for critical industrial applications. Together with 50-60 Hz operation, they help ensure process reliability and worker safety in manufacturing facilities.
By reducing nuisance trips, providing durable protection, and enabling straightforward replacement within BRX series installations, the BRX2110 lowers maintenance overhead and downtime.
