Industrial EB3030 Three-Phase Circuit Breaker

Westinghouse EB3030 is a 3-pole, 30-amp Type EB circuit breaker built for industrial electrical distribution and three-phase equipment protection. This 3-phase, 30 A device provides overload and short-circuit interruption in three-phase power systems and is commonly installed in motor control panels, HVAC equipment, industrial machinery, and commercial power distribution gear that require reliable overcurrent protection. Designed for heavy-duty industrial construction, the breaker features manual reset and switching capability and is well suited for motor branch circuits, conveyors, compressors, pumps, automation panels, and other facility circuits where uptime and safety depend on prompt interruption of fault current. Part Number EB3030 from Westinghouse identifies this 3-pole, 30 A, Type EB device for industrial and commercial electrical systems, and it can be retrofitted or replaced alongside common substitutes such as Eaton BAB3030, Siemens BQ3B030, and Square D QOB330 to support upgrades in automation panels and distribution infrastructure.
