RD316T32W - 1600 Amp Circuit Breaker

RD316T32W - 1600 Amp Circuit Breaker

When keeping an existing power distribution system operating as designed, having the correct replacement breaker matters. The RD316T32W is a 3-pole, 1600 amp RD Type molded case circuit breaker frame built for compatible R-Frame applications where matching the original form, fit, and function is essential. Designed for 40°C operation at 50/60 Hz, this thermal-magnetic breaker frame provides adjustable overcurrent protection to help coordinate with the needs of your electrical system. This breaker frame offers multiple protection settings, including adjustable long delay pickup through an adjustable rating plug, adjustable short delay pickup with either fixed short delay time (I²T response) or adjustable short delay time (flat response), and adjustable instantaneous pickup when the short delay setting is configured for instantaneous operation. These adjustment options allow the breaker to be configured for a variety of compatible applications while maintaining proper system coordination. Whether you're replacing an existing breaker during scheduled maintenance, repairing equipment after a fault, or maintaining critical electrical infrastructure, the RD316T32W is designed to deliver the compatibility and electrical ratings needed for many commercial and industrial installations. Built to last, this breaker frame is supplied without a rating plug or lug terminals, allowing those components to be selected separately to meet the specific requirements of your application.
