Eaton JD3070 - 70 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Eaton JD3070 is a 70A, 600V, 3-pole bolt-on molded case circuit breaker designed for dependable branch circuit protection in panelboards and load centers. Built to withstand the rigors of everyday electrical operation, it delivers consistent overcurrent and short-circuit protection where reliability matters most.

Precise protection with durable, vibration‑resistant mounting

• Secure bolt-on mounting provides a rigid connection to the bus, reducing the risk of loosening and ensuring dependable performance in environments with vibration or movement.
• Thermal-magnetic trip unit combines a thermal element for slow-developing overloads with a magnetic element for instantaneous response to short circuits, delivering stable, repeatable protection across temperature and load conditions.
• Three-pole design supports 3-phase applications and offers coordinated protection for multi-wire circuits common in commercial and light industrial settings.

Designed for seamless compatibility and wide-ranging use

• OEM compatibility engineered to fit matching Eaton panelboards and load centers, promoting reliable fitment and electrical performance when installed in the intended system.
• Residential, commercial, and light industrial ready ideal for protecting feeders, motors, HVAC equipment, lighting, and other branch circuits up to 70A in a variety of panel configurations.
• Bolt-on convenience makes retrofits or upgrades straightforward in existing enclosures that require a secure, non-plug-in mounting solution.
