Eaton RD316T32W 1600A 600V 3-Pole Circuit Breaker

The Eaton RD316T32W is a rugged, high-capacity circuit protection solution designed for demanding electrical environments. This 3-pole, 1600 A molded case circuit breaker uses a bolt-on mounting style to deliver a secure, vibration-resistant connection to the bus, making it a reliable choice for busy panelboards and loadcenters.

Why this breaker stands out

• Secure bolt-on mounting provides a rigid bus connection that resists loosening and arcing in vibration-prone installations, helping maintain consistent protection.
• Thermal-magnetic trip unit delivers stable, repeatable protection by combining overload (thermal) sensing with fast magnetic trip for short circuits, reducing nuisance trips and enhancing safety.
• Oil-free, molded case construction designed for long service life in residential, commercial, and light industrial settings, even in space-constrained panels.
• OEM-compatible compatibility with matching Eaton loadcenters and panelboards ensures straightforward replacement and streamlined panel upgrades.
• High-current capability rated at 1600A and 600V, making it suitable for heavy feeder applications and large branch circuits within protected electrical systems.
