E3070 - 70Amp Circuit Breaker

E3070 - 70Amp Circuit Breaker

The E3070 70 Amp 3-Pole Circuit Breaker is a Type E thermal-magnetic circuit breaker designed for applications requiring 70-amp overcurrent protection in three-phase electrical systems. Built for use in commercial and industrial power distribution equipment, this breaker combines a 3-pole configuration, 10kA interrupting capacity at 240VAC, and a non-interchangeable trip unit to help maintain the original protection characteristics of the equipment in which it is installed.

When you're maintaining existing electrical systems, compatibility matters. The E3070 is designed to provide the proper form, fit, and function for equipment that requires a Type E breaker with a 70-amp rating. Its thermal-magnetic trip mechanism responds to both overload and short-circuit conditions, helping protect connected conductors and equipment while supporting safe system operation. Rated for operation in ambient temperatures up to 40°C (104°F) and supplied with load terminals, this breaker is well-suited for replacement and maintenance applications where matching original specifications is important. Built to last and engineered for dependable service within its rated parameters, the E3070 remains a practical solution for maintaining existing electrical distribution systems.
