EB3030 - 30Amp Circuit Breaker

EB3030 - 30 Amp Circuit Breaker

The EB3030 circuit breaker is a 3-pole, 30-amp thermal-magnetic breaker designed for use in electrical distribution panels manufactured prior to 1989 that require an EB frame breaker with a non-interchangeable trip unit. Built to provide dependable overcurrent and short-circuit protection, this breaker helps maintain the safe operation of legacy electrical systems where the correct form and fit are essential. With a 10k A.I.C. interrupting rating at 240VAC, the EB3030 is designed to interrupt fault currents within its rating while maintaining compatibility with older panelboard configurations. Rated for operation at 40°C, the breaker is suited for typical electrical room environments. This unit also includes load terminals, allowing for straightforward installation when replacing an existing breaker of the same type. Like many electrical components built during this era, the EB frame series was manufactured with durability in mind, making it a practical solution when maintaining or servicing established power distribution equipment.
