MXD63B700 - 700Amp Circuit Breaker

MXD63B700 - 700Amp Circuit Breaker

Need an MXD63B700 circuit breaker to keep your existing electrical system running as intended? Finding the right replacement starts with matching specifications, and this 700 Amp, 3-Pole Molded Case Circuit Breaker is designed for applications that require the MXD6 series configuration. Whether you're maintaining commercial electrical equipment, servicing an industrial power distribution system, or replacing an existing breaker, the MXD63B700 offers the specific electrical ratings and physical dimensions needed for compatible installations.

What makes the MXD63B700 worth considering? It's all about getting the right fit for your equipment. This breaker features a non-interchangeable trip unit and includes load-side lugs, helping maintain the original connection arrangement where compatible. Its interrupting ratings are 25kA at 600VAC, 50kA at 480VAC, and 65kA at 240VAC, giving you clear ratings to match your system requirements. There's also a 30kA rating at 250VDC for applicable 2-pole configurations. At 16 inches high, 9 inches wide, and 6 inches deep, you can compare its physical size with your existing installation before selecting a replacement. Built for long-term use in its intended applications, the MXD63B700 is a sensible choice for maintaining legacy electrical systems where matching the original breaker's form, fit, and function matters.
