Square D EGB34070SA E-Frame Molded Case Circuit Breaker – 3 Pole – 70A – Bolt-On – Thermal Magnetic – 120VAC Shunt Trip

The Square D EGB34070SA is a molded case circuit breaker designed for commercial and industrial power distribution systems requiring reliable protection and remote tripping capability. Manufactured by Schneider Electric, this 3-pole, 70A E-Frame breaker delivers dependable thermal-magnetic protection for overloads and short-circuit conditions in three-phase electrical applications.

This model includes a factory-installed 120VAC shunt trip, enabling remote or automated disconnection for emergency power-off systems, safety interlocks, and building automation control. It mounts securely into NF panelboards using a bolt-on connection and is designed for stable operation in demanding electrical environments.

Due to the integrated shunt trip mechanism, the breaker features a wider 3.92-inch footprint compared to standard models, ensuring proper accommodation of the accessory within NF panelboard configurations.

With a high interrupting rating of 65kA at 240VAC and 35kA at 480Y/277VAC, the EGB34070SA provides strong fault protection performance for commercial distribution systems. A Visi-Trip indicator allows quick visual identification of tripped circuits, improving maintenance efficiency and system uptime.
