RXD63B160 - 1600Amp Circuit Breaker

RXD63B160 - 1600Amp Circuit Breaker

When you need a 1600-amp molded-case circuit breaker that matches the specifications of an existing electrical distribution system, the RXD63B160 offers the form, fit, and functionality required for compatible installations. Built on the RD2000A frame, this 3-pole thermal-magnetic circuit breaker is designed to protect electrical systems from overloads and short circuits while maintaining the original protection characteristics through its non-interchangeable trip unit. Whether you're replacing a failed breaker during maintenance or sourcing a compatible unit for an existing commercial or industrial power system, matching the correct ratings is essential. The RXD63B160 provides interrupting capacities of 25kA at 600VAC, 50kA at 480VAC, and 65kA at 240VAC, making it suitable for applications designed within these electrical ratings. Its molded-case construction is built to last and is intended for dependable service in demanding electrical environments. Before installation, always verify compatibility with your equipment, including the frame size, amperage, voltage, interrupting rating, and trip characteristics.
