Rated continuous current is 40 A, with an adjustable trip range from 60 A minimum to 480 A maximum — meaning it protects downstream conductors and equipment against overloads and short circuits up to that full-scale value.
This MCCB's interrupting capacity varies by system voltage: 440 kA at 240 V AC, 330 kA at both 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V. At 690 V the 52.5 kA figure still covers most industrial distribution fault levels; the 440 kA at 240 V is high enough for large transformer secondaries or high-fault utility feeds. A communication function is built in — enables remote monitoring or integration with a building management system via optional modules.
Standard DIN-rail or screw-mount footprint for a 3-pole MCCB in a SENTRON distribution board. The 105 mm width matches the usual 4-module spacing on a DIN rail; check your existing busbar or panel cutout for clearance on the 181 mm height.
