MXD63B700L - 700Amp Circuit Breaker

MXD63B700L - 700Amp Circuit Breaker

Need an MXD63B700L 700 Amp circuit breaker to keep your existing electrical system running as intended? Finding the right replacement starts with matching the specifications, and this MXD6 molded-case circuit breaker is designed for commercial and industrial electrical distribution systems that require this specific configuration. With a 700-amp current rating, 3-pole design, and non-interchangeable trip unit, the MXD63B700L provides circuit protection for compatible equipment while maintaining the original electrical setup. It features interrupting ratings of 25kA at 600VAC, 50kA at 480VAC, and 65kA at 240VAC, along with a 30kA rating at 250VDC for applicable 2-pole configurations. Both line-side and load-side lugs are included, giving you the connection components specified for this breaker. Built to last, its durable molded case construction meets the demands of its intended electrical application. When you're working with an established installation, dimensions matter as much as electrical ratings. Measuring 16 inches high, 9 inches wide, and 6 inches deep, this breaker offers a defined physical configuration for evaluating replacement fit. Whether you're maintaining an industrial facility, servicing commercial distribution equipment, or replacing an existing MXD63B700L, this model is worth considering when an exact match in form, fit, and function is required.
