Eaton MDL3700W - 700 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Eaton MDL3700W is a rugged 3-pole bolt-on molded case circuit breaker engineered to deliver reliable branch circuit overcurrent and short-circuit protection in panelboards and load centers. With a robust 700 A rating at up to 600 V, it’s purpose-built for demanding residential, commercial, and light industrial applications where steady protection and solid performance matter most.

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection, helping maintain consistent electrical contact and reducing the risk of connection loosening in installations subject to movement or vibration.
• Thermal-magnetic trip unit delivers stable, repeatable protection by combining heat-based sensing with magnetic tripping, delivering fast response to short circuits while preventing nuisance trips during normal loading.
• OEM-compatible design is engineered to pair with matching Eaton OEM load centers and panelboards, enabling straightforward, plug-and-play replacements and a harmonious protection scheme across your distribution system.
• High-capacity, multi-pole protection supports complex branch circuits and multi-wire configurations, making it suitable for service panels, feeders, and subpanel installations in larger or retrofit projects.
• Durable construction for challenging environments—built to endure the realities of residential, commercial, and light industrial settings while delivering dependable, long-term performance.

Ideal for upgrades, retrofits, or new panel installations, the MDL3700W is designed to safeguard conductors and equipment from overcurrent events. It’s particularly well-suited for panelboards that require a robust, bolt-on breaker with a proven thermal-magnetic protection scheme, enabling consistent protection in high-current applications and environments where vibration or movement is a factor.
