EB2030L - 30Amp Circuit Breaker

EB2030L - 30 Amp Circuit Breaker

The EB2030L circuit breaker is a 2-pole, 30-amp thermal-magnetic circuit breaker designed for dependable circuit protection in compatible legacy electrical distribution systems. Built on the EB frame platform, this breaker is intended for installation in electrical panels manufactured prior to 1989 that require breakers with non-interchangeable trip units. It provides reliable protection against overloads and short circuits in 120/240VAC systems, helping safeguard wiring and connected equipment from electrical faults. Rated for operation at 40°C, the EB2030L is engineered for everyday service conditions commonly found in residential, commercial, and light industrial electrical panels. The breaker includes both line and load terminals, allowing straightforward installation and secure conductor connections. With a 10kA interrupting rating, it is designed to safely interrupt fault currents within its specified rating while maintaining compatibility with existing EB frame panelboards.

Built with durability in mind, the EB2030L follows the traditional thermal-magnetic protection design that electricians and maintenance professionals have relied on for decades. For facilities maintaining older panel systems, this breaker offers the correct form, fit, and function replacement needed to keep electrical distribution equipment operating safely and as intended.
