Eaton RD316T35W 1600A 600V 3-Pole Circuit Breaker

Engineered by Eaton and featured in the AmpState lineup, the RD316T35W is a robust 3-pole bolt-on molded case circuit breaker designed for dependable branch-circuit overcurrent and short-circuit protection in panelboards and loadcenters. Built to withstand demanding power environments, this unit combines a secure mounting method with precise trip performance to safeguard large feeders and three-phase equipment.

Secure bolt-on mounting provides a rigid, vibration-resistant bus connection that maintains electrical integrity in environments prone to movement or vibration. This design reduces the risk of loose connections and provides lasting, reliable protection.

Thermal-magnetic trip unit delivers stable, repeatable protection across a broad range of fault currents. The system responds quickly to short circuits while minimizing nuisance trips, helping keep downtime and maintenance costs in check.

Three-pole configuration for balanced protection ensures simultaneous disconnection of all phases in three-phase systems, essential for motors, compressors, and other multi-phase loads typical in commercial and light industrial settings.

High-capacity ratings: 1600A amperage and 600V interruption capability empower you to protect large feeders and high-demand circuits without compromising safety or performance.

OEM-ready compatibility: designed to work with matching Eaton OEM load centers and panelboards, enabling seamless integration into existing electrical infrastructures with coordinated protection.

Versatile application: suitable for residential, commercial, and light industrial applications where reliable overcurrent and short-circuit protection is essential for safe, continuous operation.

Practical use cases and installation notes

Ideal for upgrading or replacing aging protection in panelboards where large feeders or motor-driven loads demand robust protection. The bolt-on design delivers a secure connection ready for challenging environments, while the 3-pole configuration provides comprehensive three-phase protection. When integrating into OEM load centers, confirm compatibility with your specific panel model to ensure proper fit and coordination with existing protective devices. For installations in three-phase systems, the RD316T35W interrupts all conductors together to prevent phase-to-phase faults and protect downstream equipment.

Who benefits most

Electrical engineers, facilities managers, and electricians overseeing mid-to-large commercial projects, light industrial facilities, or robust three-phase residential setups will value the combination of high current capability, reliable protection, and seamless OEM compatibility offered by the Eaton RD316T35W.

Why this model stands apart

Unlike plug-in alternatives, the bolt-on RD316T35W provides a more secure mechanical connection to the panel bus, enhancing long-term protection reliability in environments subject to vibration. The thermal-magnetic trip unit delivers consistent, repeatable protection performance, reducing nuisance trips while ensuring fast interruption for motor loads and other high-demand circuits.

Maintenance and tips

Follow panel manufacturer torque recommendations for mounting hardware and inspect for signs of wear, corrosion, or overheating at the connection points. Use only compatible Eaton OEM components to preserve protective coordination and preserve the panel’s listing and safety performance.
