EB3070L - 70Amp Circuit Breaker

EB3070L - 70Amp Circuit Breaker

When maintaining older electrical distribution systems, finding the correct replacement breaker is often the key to keeping equipment operating as intended. The EB3070L 70 Amp 3-Pole Type EB Circuit Breaker was designed for use in compatible electrical panelboards manufactured before 1989, making it a practical choice for facilities that continue to rely on proven legacy equipment.

This thermal-magnetic circuit breaker provides protection against overloads and short circuits while matching the form, fit, and function requirements of compatible Type EB panelboards. With a 70-amp rating, 3-pole configuration, and 10kA interrupting capacity at 240VAC, the EB3070L is commonly used in commercial, industrial, institutional, and municipal electrical systems where maintaining existing infrastructure is a priority.

Many facilities continue to depend on electrical equipment that has been in service for decades. In these environments, maintaining compatibility is often more important than changing equipment. Whether you're replacing a failed breaker during routine maintenance, restoring an older electrical system, or sourcing a hard-to-find component for an existing installation, the EB3070L provides the ratings, configuration, and compatibility needed to help keep your electrical distribution system operating as intended.
