EB2090L - 90Amp Circuit Breaker

EB2090L - 90 Amp Circuit Breaker

The EB2090L circuit breaker is a 2-pole, 90-amp thermal-magnetic breaker built for use in electrical panels that require an EB-frame breaker, particularly panelboards manufactured before 1989. It provides dependable circuit protection by responding to both overloads and short circuits, helping maintain safe operation within compatible electrical systems.

This breaker uses a non-interchangeable trip unit, meaning the trip characteristics are fixed and designed specifically for the breaker’s intended application. With a 10k A.I.C. rating at 120/240VAC, it meets the interrupting capacity commonly required for many residential and light commercial electrical distribution setups.

The EB2090L also includes line and load terminals, which helps simplify installation in compatible panels. Rated for operation at 40°C, it is designed to function reliably in standard electrical equipment environments. Like many breakers built for legacy systems, its construction reflects the long-lasting design typically found in electrical distribution components.

Key Features and Benefits

• 90 Amp Rating – Designed for circuits requiring 90-amp protection.
• Two-Pole Breaker – Provides protection for 120/240VAC electrical circuits.
• Thermal-Magnetic Operation – Thermal protection reacts to sustained overloads while magnetic protection responds quickly to short circuits.
• 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.
• Line and Load Terminals Included – Supports straightforward installation in compatible panels.
• 40°C Rated – Suitable for typical electrical enclosure operating temperatures.
• Built for Legacy EB Panels – Designed for panelboards originally produced before 1989 that require EB-frame breakers.
