RJF36200CU44ABDYP - 2000 Amp Circuit Breaker with Lockoff and Overcurrent Trip Switch (SDE)

RJF36200CU44ABDYP - 2000 Amp Circuit Breaker with Lockoff and Overcurrent Trip Switch (SDE)

When your electrical system demands dependable protection at high current levels, the RJF36200CU44A PowerPact® R-Frame circuit breaker is built to deliver. Rated at 2000 amps with a 3-pole configuration, this breaker is designed for large commercial and industrial power distribution systems where reliability isn't optional—it's expected. Whether you're protecting a main distribution panel, switchboard, or other critical equipment, the RJF36200CU44A helps minimize downtime by responding quickly and accurately to overloads and fault conditions. What sets this model apart is its Micrologic interchangeable ammeter electronic trip unit (Code 6.0A), which provides advanced protection and greater visibility into system performance. With Long Time, Short Time, Instantaneous, and Ground Fault protection built in, the breaker helps coordinate protection throughout your electrical system, reducing the likelihood of unnecessary trips while still responding when it matters most. Its 100% rated design also allows continuous operation at its full current rating when installed in equipment designed for 100% rated applications, making it an excellent choice for demanding installations operating in 40°C ambient environments.
