EB2100L - 100Amp Circuit Breaker

EB2100L - 100 Amp Circuit Breaker

The EB2100L circuit breaker is a 2-pole, 100-amp thermal-magnetic circuit breaker designed for use in electrical distribution panels manufactured before 1989 that require an EB frame breaker. Built to provide dependable overcurrent and short-circuit protection in 120/240VAC systems, this breaker helps maintain safe electrical operation by interrupting current flow when abnormal conditions occur. The EB2100L includes line and load terminals for straightforward installation and is rated for operation in environments up to 40°C (104°F). Its non-interchangeable trip unit design ensures consistent protection settings aligned with the breaker’s rated specifications. Constructed with durable internal components and designed to fit legacy panel configurations, this breaker provides the correct form, fit, and functional replacement needed to maintain existing electrical infrastructure.

Where It Works Best

• The EB2100L 2-pole 100A breaker is commonly used in electrical systems where panelboards require EB frame circuit breakers, particularly in installations originally built prior to 1989. Typical applications include:
• Commercial and light industrial electrical panels
• Legacy building distribution systems
• Electrical maintenance and repair projects
• Service equipment and sub-panel protection in compatible panels
• It is intended for situations where maintaining correct physical fit and electrical ratings within an existing panelboard is essential. By matching the original frame type and specifications, the EB2100L helps support safe and reliable operation of established electrical infrastructure.
