E2070 - 70Amp Circuit Breaker

E2070 - 70 Amp Circuit Breaker

The E2070 70-amp 2-pole circuit breaker is designed to provide dependable overcurrent protection for electrical distribution systems operating at 120/240VAC. Built with a thermal-magnetic trip mechanism, this breaker responds to both sustained overloads and short-circuit conditions, helping protect wiring and connected equipment from damage. Its non-interchangeable trip unit ensures the breaker maintains its calibrated protection characteristics throughout its service life. Rated for 10kA interrupting capacity and 40°C operating conditions, the E2070 is commonly used in existing panelboards and load centers that require a Type E frame breaker with a 70-amp rating. Load terminals are included, allowing straightforward installation where this form, fit, and function are required in legacy electrical systems. Built to last, this breaker supports continued operation and maintenance of compatible electrical distribution equipment.

Key Features and Benefits
