EB2070L - 70Amp Circuit Breaker

EB2070L - 70 Amp Circuit Breaker

The EB2070L circuit breaker is a 2-pole, 70-amp thermal-magnetic breaker designed for use in legacy electrical distribution systems and panelboards manufactured prior to 1989. Built with a non-interchangeable trip unit and rated for operation at 120/240VAC with a 10kA interrupting capacity, this breaker provides dependable overcurrent protection for branch circuits in commercial, industrial, and residential applications where EB-frame breakers are required. Its thermal-magnetic design responds to both sustained overloads and instantaneous short-circuit conditions, helping protect conductors and connected equipment from electrical faults. The EB2070L includes factory-installed line and load terminals for straightforward installation and secure conductor connections. With its defined form, fit, and electrical ratings, this breaker serves as a functional replacement in compatible EB-frame panelboards and electrical systems that rely on this breaker style.

Electrical components like the EB2070L were built with durability in mind, allowing them to continue supporting legacy electrical infrastructure where proper compatibility and ratings must be maintained.

Key Features and Benefits

• 70 Amp, 2-Pole Configuration: Designed to protect 120/240VAC circuits requiring two-pole overcurrent protection.
• Thermal-Magnetic Trip Mechanism: Combines thermal response for overload protection with magnetic response for short-circuit conditions.
• 10kA Interrupting Capacity: Rated to safely interrupt fault currents up to 10,000 amps at 120/240VAC.
• Non-Interchangeable Trip Unit: Fixed trip design maintains consistent protection characteristics.
• Includes Line and Load Terminals: Allows secure wire termination and simplified installation.
• EB Frame Compatibility: Engineered for panelboards designed to accept EB-frame circuit breakers.
• 40°C Rated Operation: Suitable for environments where standard 40°C ambient rating is required.
• Designed for Legacy Panel Systems: Intended for panels manufactured before 1989 that require EB-series breakers.
