RD320T32W - 2000 Amp Circuit Breaker

RD320T32W - 2000 Amp Circuit Breaker

When you're maintaining or servicing an existing electrical distribution system, using the correct replacement components matters. The RD320T32W is a 3-pole, 2000A R-Frame thermal-magnetic molded case circuit breaker frame designed to provide the proper form, fit, and function for compatible installations. Built for 50/60 Hz operation at 40°C, this breaker frame offers adjustable overcurrent protection options, allowing it to be configured to meet application needs when paired with the appropriate accessories. The RD320T32W features adjustable long-delay pickup using a compatible rating plug, adjustable short-delay pickup with either I²T or flat response, and adjustable instantaneous pickup when the short-delay setting is configured for instantaneous operation. Its interrupting ratings of 50 kA at 600 VAC, 65 kA at 480 VAC, and 125 kA at 240 VAC make it suitable for a wide range of commercial and industrial power distribution systems.

Material Compliance and Certifications

• Application: The RD320T32W is manufactured for use in commercial and industrial electrical distribution systems and is designed for applications that require an R-Frame thermal-magnetic molded-case circuit breaker.
• Installation Requirements: Always confirm compatibility with your equipment and follow applicable electrical codes and manufacturer installation requirements before placing the breaker into service.
  

Where It Works Best

• The RD320T32W is commonly used in industrial facilities, manufacturing plants, commercial buildings, institutional campuses, utility infrastructure, and other high-capacity power distribution systems that use compatible R-Frame molded-case circuit breakers. It is well-suited for maintenance, repair, and replacement projects where preserving the original equipment's form, fit, electrical ratings, and protection characteristics is essential. Because this unit is supplied as a frame only, it is intended for applications in which compatible rating plugs and lug terminals are installed separately.
