EB3015L - 15Amp Circuit Breaker

EB3015L - 15 Amp Circuit Breaker

The EB3015L circuit breaker is a 3-pole, 15-amp thermal-magnetic breaker built for electrical panels that use the EB frame design. It’s commonly installed in panelboards manufactured before 1989 where this specific breaker style was originally specified. When an existing breaker needs to be replaced, matching the correct frame and rating is important so the device fits properly and functions the way the system was designed to operate.

This breaker provides standard protection against overload conditions and short circuits through its thermal-magnetic trip mechanism. The thermal portion responds to prolonged overcurrent situations, while the magnetic portion reacts quickly during fault events. The EB3015L carries an interrupting rating of 10kA at 240VAC, which makes it suitable for branch circuit protection in many commercial and light industrial installations. It uses a non-interchangeable trip unit, meaning the 15-amp rating is factory set. Line and load terminals are included, and the breaker is rated for operation in environments up to 40°C (104°F). Breakers built for this type of equipment are made with durable internal components and are intended for long-term service in compatible systems.

Key Features and Benefits

• Three-Pole Breaker Design Provides simultaneous protection across three phases in applicable electrical systems.
• 15 Amp Rating Appropriate for circuits where lower current protection is required.
• Thermal-Magnetic Trip Operation Handles both sustained overloads and instantaneous short-circuit conditions.
• 10kA Interrupting Capacity at 240VAC Rated to safely interrupt fault current within specified limits.
• EB Frame Construction Designed to fit panelboards that were built to accept EB-series breakers.
• Factory-Set Trip Unit The trip unit is non-interchangeable and calibrated at 15 amps.
• Line and Load Terminals Included Connection points are provided with the breaker.
• 40°C Ambient Rating Suitable for standard electrical room environments.
• Form, Fit, and Function Compatibility Intended for panels manufactured prior to 1989 that require this breaker configuration.

Where It Works Best

• The EB3015L 15A 3-pole circuit breaker is typically found in facilities that continue to operate legacy electrical panels requiring EB-frame breakers.
• Commercial buildings with older distribution panels
• Industrial facilities maintaining existing electrical infrastructure
• Maintenance replacements in panelboards manufactured before 1989
• Systems where the original breaker design must be matched for proper fit
• Using the correct breaker type helps maintain proper alignment with the panel’s bus connection and ensures the protective device operates as intended within the system.
