EB2020 - 20Amp Circuit Breaker

EB2020 - 20 Amp Circuit Breaker

The EB2020 2-pole circuit breaker is designed to provide dependable overcurrent protection for electrical distribution systems that utilize EB-frame breakers. Rated at 20 amps with a 10kA interrupting capacity at 120/240VAC, this thermal-magnetic breaker helps protect branch circuits from overloads and short circuits in legacy panelboards manufactured prior to 1989. Its non-interchangeable trip unit maintains consistent trip calibration, while the included load terminals simplify installation and connection. Built to operate at a 40°C ambient rating, the EB2020 breaker is intended for applications where maintaining proper form, fit, and function in existing electrical systems is essential. Like many breakers produced for long-term service environments, units in this class were built with durability in mind and intended for extended operational use in compatible electrical panels.

Key Features and Benefits

• 2-Pole Configuration – Provides protection across two circuits or a 120/240V branch circuit.
• 20 Amp Rating – Suitable for circuits requiring moderate current protection in residential or light commercial systems.
• Thermal-Magnetic Protection – Combines thermal overload protection with instantaneous magnetic trip response for short circuits.
• 10kA Interrupting Capacity – Rated to safely interrupt fault currents up to 10,000 amps at 120/240VAC.
• Non-Interchangeable Trip Unit – Factory-set trip characteristics remain fixed for consistent protection.
• Includes Load Terminals – Designed to allow straightforward conductor termination during installation.
• Designed for Pre-1989 Panels – Matches the form and mounting style required for EB-frame panelboards produced before 1989.
• 40°C Ambient Rating – Intended for use in environments where panelboard temperatures may reach typical operating limits.

Where It Works Best

• The EB2020 circuit breaker is intended for maintenance, repair, or replacement in electrical panels originally designed to accept EB-frame breakers, particularly those manufactured prior to 1989.
• Legacy residential electrical panels
• Commercial facilities maintaining existing EB-frame distribution equipment
• Service and maintenance projects requiring a compatible replacement breaker
• Electrical systems where maintaining the original panel configuration is necessary
• By matching the correct frame type, pole configuration, and electrical ratings, this breaker helps ensure the existing system continues to operate as designed while maintaining proper circuit protection.
