Eaton Cutler-Hammer RDC316T32W 1600A 3-Pole Molded Case Circuit Breaker – 600VAC – Bolt-On

The Eaton Cutler-Hammer RDC316T32W molded case circuit breaker is engineered for high-performance electrical protection in industrial and commercial power distribution systems. Built on the RDC frame platform, this breaker features the Digitrip RMS 310 electronic trip unit, delivering accurate RMS sensing and adjustable protection parameters.

This model incorporates LSI protection functions—Long Delay, Short Delay, and Instantaneous—allowing system engineers to coordinate protection settings for optimal selectivity and equipment protection. With a 1600-ampere rating at 40°C, the breaker is suitable for high-capacity feeder circuits, switchboards, and motor control centers.

Compared with standard RD series models, the RDC version offers higher interrupting capacity, making it appropriate for installations with higher available fault current.
