EB3060L - 60Amp Circuit Breaker

EB3060L - 60 Amp Circuit Breaker

The EB3060L circuit breaker is a 3-pole, 60-amp thermal-magnetic breaker designed for use in compatible EB-frame panelboards, particularly those manufactured prior to 1989. It provides standard branch or feeder circuit protection by responding to both prolonged overload conditions and sudden short circuits. The thermal-magnetic trip mechanism combines two protective functions in one unit: a thermal element that reacts to sustained current increases and a magnetic element that responds quickly during fault conditions.

This breaker uses a non-interchangeable trip unit, meaning the trip rating is fixed at 60 amps as originally designed. That configuration helps maintain the intended protection characteristics within systems built around EB-frame breakers. With a 10kA interrupting capacity at 240VAC, the EB3060L is suited for many commercial and industrial distribution setups where legacy equipment remains in service.

The breaker includes line and load terminals and is rated for operation in environments up to 40°C (104°F). Its form and dimensions were designed to match EB-series panelboards produced before 1989, making it a practical option when maintaining or servicing existing electrical infrastructure. Breakers from this generation were manufactured with durable materials and construction intended for long service life when used within their rated electrical limits.

Material Compliance and Certifications

• Manufacturing Standards: The EB3060L circuit breaker was manufactured in accordance with the electrical safety and performance standards applicable at the time of its production.
• Construction Materials: Molded case breakers in this class were produced using industry-accepted insulating materials, conductive components, and mechanical trip assemblies designed for use in commercial and industrial power distribution equipment.
• Operational Safety: When installed in compatible systems and used within its rated limits, the breaker supports safe circuit protection consistent with those standards.
  

Where It Works Best

• Commonly used in facilities that still operate EB-series panelboards.
• Installed during maintenance or repair work where maintaining the original breaker type is necessary.
• Commercial buildings with legacy electrical panels.
• Industrial facilities operating long-standing distribution equipment.
• Electrical maintenance projects requiring EB-frame replacement breakers.
• Service repairs where panel compatibility must be preserved.
• Best used in systems that require the original EB-frame configuration for proper fit and function because it was designed specifically for pre-1989 panelboards.
