700 A electronic-trip breaker for panelboard and switchboard feeder positions
The MGP26700 is a PowerPacT M electronic-trip circuit breaker rated 700 A continuous, 3-pole, with an interrupting capacity of 18 kA at 600 VAC. The unit-mount form factor with lugs off end suits it for panelboard or switchboard feeder positions where a compact, field-replaceable breaker is preferred over a fixed-mount drawout unit.
Selectivity and coordination considerations
For a 700 A feeder, that rating typically covers service-entrance and distribution panel applications on transformer secondaries up to about 500 kVA. The electronic trip unit allows adjustable long-time, short-time, and instantaneous pickup — critical for achieving selective coordination with downstream branch breakers.
