RD316T36W - 1600 Amp Circuit Breaker

RD316T36W - 1600 Amp Circuit Breaker

When your electrical distribution system requires dependable overcurrent and ground fault protection, the RD316T36W molded case circuit breaker delivers the ratings and functionality needed to keep compatible equipment operating as intended. This 3-pole, 1600 amp R-Frame thermal-magnetic circuit breaker is designed for applications where precise protection settings are important, making it well-suited for large commercial and industrial power distribution systems. What makes the RD316T36W especially versatile is its wide range of adjustable protection functions. The included 1600A rating plug allows long delay pickup to be adjusted for proper coordination with downstream equipment, while the adjustable short delay pickup can be configured for either I²T response or flat response to better match system requirements. Adjustable ground fault pickup and adjustable ground fault delay add another level of flexibility, helping protect equipment while reducing unnecessary interruptions. Instantaneous protection is also built in to respond quickly during severe fault conditions. Designed for 50/60Hz operation at 40°C, this breaker is built to last and serves as a dependable form, fit, and functional replacement for compatible R-Frame installations.
