The Westinghouse EA3015 U Circuit Breaker is a 15A, 3-pole, 240V AC low-voltage device designed to protect three-phase electrical systems in industrial and commercial environments. It is commonly used in motor control panels, HVAC equipment, industrial machinery, and facility distribution panels to provide overload and short-circuit protection, with manual reset and switching capabilities for maintenance and safe operation. Common replacements include Eaton BAB3015, Siemens BQ3B015, and Square D QOB315, underscoring its role as a cross-brand option for legacy systems.
