EB1020L - 20Amp Circuit Breaker

EB1020L - 20 Amp Circuit Breaker

The EB1020L 20-amp single-pole circuit breaker is designed for use in electrical panels that require the EB frame style commonly installed before 1989. This thermal-magnetic circuit breaker provides branch circuit protection in 120VAC systems by responding to both sustained overload conditions and sudden short-circuit faults. The breaker uses a fixed, non-interchangeable trip unit calibrated at the factory to maintain consistent protection characteristics. With a 10kA interrupting rating at 120VAC, the EB1020L is intended for installations where matching the original panel specifications is important. Line and load terminals are included, helping electricians connect conductors quickly during replacement or maintenance. Built with durable internal components, this breaker is designed to provide dependable circuit protection in compatible legacy electrical distribution equipment.

Key Features and Benefits

• 20 Amp Rating – Provides branch circuit protection for 120VAC electrical systems.
• Single-Pole Breaker – Designed to protect a single energized conductor in compatible panelboards.
• Thermal-Magnetic Operation – Responds to prolonged overloads through thermal sensing and reacts instantly to short circuits using magnetic trip action.
• 10kA Interrupting Capacity – Rated to safely interrupt fault currents up to 10,000 amperes at 120VAC.
• Non-Interchangeable Trip Unit – Factory-set trip calibration helps maintain consistent protection settings.
• Line and Load Terminals Included – Allows straightforward conductor termination during installation.
• EB Frame Compatibility – Manufactured to match the form and fit required for EB-frame panelboards produced before 1989.
• Durable Construction – Built with long-lasting materials intended for continued service in properly matched systems.

Where It Works Best

• The EB1020L EB-frame circuit breaker is commonly used in older commercial and industrial electrical systems where original EB-style breakers were installed. It works well for maintenance projects involving legacy panelboards manufactured prior to 1989 where maintaining correct form and fit is necessary. Electricians, maintenance technicians, and facility managers often use breakers like the EB1020L when servicing existing electrical distribution equipment that requires the same frame type, amperage rating, and interrupting capacity.
