EB3070 - 70Amp Circuit Breaker

EB3070 - 70Amp Circuit Breaker

When maintaining older electrical distribution equipment, finding the right replacement breaker is often about more than matching the amp rating. The EB3070 Type EB circuit breaker is designed for use in compatible panelboards manufactured before 1989, making it a practical choice for facilities that continue to rely on legacy electrical systems. Whether you're performing scheduled maintenance, replacing a failed breaker, or keeping existing equipment in service, this 70 amp, 3-pole breaker provides the form, fit, and function required for compatible installations.

The EB3070 features a thermal-magnetic trip mechanism, helping protect electrical circuits from overloads and short-circuit conditions. Its non-interchangeable trip unit maintains compatibility with the original equipment design, while the included load terminals help streamline installation in approved applications.

Many facilities still depend on electrical equipment that has been operating reliably for decades. In these environments, maintaining compatibility is often the key to efficient maintenance and repairs. The EB3070 provides the ratings and configuration needed for existing Type EB systems, helping electricians, contractors, and facility managers keep critical electrical infrastructure operating as intended.
