Eaton BAB3070HS - 70 A, 240 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Engineered for dependable branch-circuit protection, the Eaton BAB3070HS 70A, 240V, 3-pole bolt-on molded case circuit breaker delivers precise thermal-magnetic protection for panelboards and loadcenters. Its secure bolt-on design creates a rigid, vibration-resistant bus connection that stays tight through installation, maintenance, and operation in demanding environments.

Why the BAB3070HS stands out

• Secure bolt-on mounting provides a rigid, vibration-resistant connection to the bus, minimizing loosening and ensuring consistent performance in panels subject to vibration or rough servicing.
• Thermal-magnetic trip unit delivers stable, repeatable protection—responding to sustained overloads with thermal sensing and to high fault currents with magnetic actuation for fast isolation.
• Three-pole configuration supports three-phase systems or multi-pole protection within single-panel applications, enabling versatile protection schemes.
• 70A at 240V suits moderate-load branch circuits commonly found in residential, commercial, and light industrial settings.
• OEM-compatible designed to pair with matching Eaton OEM loadcenters and panelboards, ensuring proper fit, electrical performance, and seamless integration.
• Broad application range ideal for protective needs in homes, small businesses, and equipment rooms where reliable overcurrent and short-circuit protection matters.

What problems it solves

The BAB3070HS helps prevent electrical damage and downtime by quickly interrupting power during overloads and short circuits, protecting wiring, devices, and downstream equipment. Its robust bolt-on design reduces the risk of loose connections over time, while the thermal-magnetic trip delivers predictable behavior under varying fault conditions—so you can rely on consistent protection across service cycles.
