E3070 - 70Amp Circuit Breaker Description
E3070 - 70 Amp Circuit Breaker
The E3070 circuit breaker is a 70-amp, 3-pole thermal-magnetic circuit breaker designed for dependable protection in electrical distribution systems operating up to 240VAC. Built on the E-frame platform, this breaker features a non-interchangeable trip unit calibrated to provide consistent overcurrent and short-circuit protection for connected equipment and circuits. Its thermal-magnetic design combines long-time overload protection with instantaneous response to short circuits, helping maintain safe operation within panelboards and other legacy power distribution setups. Rated for operation at 40°C, the E3070 is commonly used as a direct replacement where matching frame size, pole configuration, and interrupting capacity are required. The unit includes load terminals for straightforward installation and secure conductor connections. Built with durability in mind, breakers in this class are designed to provide dependable service over many years when used within their rated conditions.
