RD320T35W - 2000 Amp Circuit Breaker

RD320T35W - 2000 Amp Circuit Breaker

When keeping an existing power distribution system operating as intended, using the correct replacement components matters. The RD320T35W is a 3-pole, 2000-amp Type RD R-Frame molded-case circuit breaker frame designed for compatible commercial and industrial electrical systems operating at 50/60 Hz. Built for form, fit, and functional replacement, this breaker frame provides the foundation for configuring circuit protection to match your application through the use of a compatible rating plug (sold separately). This thermal-magnetic breaker frame includes adjustable protection functions that make it well-suited for demanding power distribution applications. Long delay pickup is adjustable through the rating plug, while short delay pickup can be configured using either a fixed-time I²T response or an adjustable flat response. It also features adjustable ground fault pickup and adjustable ground fault timing, helping support proper coordination with other protective devices throughout the electrical system. Designed for operation in 40°C ambient environments, the RD320T35W is built to last and is intended for maintaining compatible legacy electrical equipment—not replacing an entire system with a different design.

Where It Works Best

• The RD320T35W is commonly used in commercial buildings, manufacturing facilities, industrial plants, healthcare facilities, educational campuses, and other large electrical distribution systems that utilize compatible R-Frame molded case circuit breakers. Because it is supplied as a frame only, it's an ideal solution when replacing a damaged breaker frame or maintaining existing switchgear, switchboards, and panelboards while using the appropriate rating plug and lug configuration for the application.
