Square D EDB16070 - 70 A, 347 V, 1-Pole Bolt-On Circuit Breaker | AmpState

The Square D EDB16070 is a purpose-built, 1-pole bolt-on molded-case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. With a 70 A rating and a 347 V operating capacity, this unit powers reliable protection for a wide range of electrical installations while maintaining a compact, space-saving footprint in the panel.

Why this model stands out

• Secure bolt-on mounting provides a rigid, vibration-resistant connection to the bus, helping maintain consistent electrical contact even in environments with equipment vibration or movement.
• Thermal-magnetic trip unit offers stable, repeatable protection by responding to both overload (thermal) and short-circuit (magnetic) conditions, reducing nuisance trips and enhancing system reliability.
• OEM-compatible design is tailored to match Square D panelboards and loadcenters, ensuring a clean fit and straightforward replacement in existing systems.
• Versatile application suitable for residential, commercial, and light industrial settings, where dependable circuit protection is essential for safety and uptime.

Practical use cases

• Upgrading or maintaining a panelboard where a 70 A, 1-pole device is required to protect a single high-demand circuit or branch running at 347 V.
• Installing in new or retrofit installations where a bolted, vibration-resistant breaker minimizes movement and maintains reliable bus contact over time.
• Replacing aging or worn breakers in commercial or light-industrial panels to restore quick-tripping protection without changing the panel layout.
