Product details

Its interrupting capacity hits 187 kA at 240 V and still holds 121 kA at 415 V and 440 V — meaning it handles high-fault scenarios without cascading upstream. That simplifies panel layout — no need to oversize for a hot enclosure next to drives or transformers.

Footprint and integration

Fits standard panel cutouts for 3-pole SENTRON MCCBs. Spring-cage terminals accept 0.2–2.5 mm² solid or ferruled stranded — strip length 8 mm avoids whiskers under the cage. No undervoltage release fitted on this variant. Power loss is 1.6 W maximum — negligible for thermal budgeting even in densely packed panels.

Frequently asked questions

What is the interrupting capacity of this MCCB at 480 V?

The evidence does not list a 480 V rating. At 440 V it is 121 kA; at 500 V it drops to 75.6 kA. For a 480 V system, the 415 V / 440 V figure (121 kA) is the closest reference — verify coordination with your available fault current.

Will this breaker fit a panel cutout for a 5SQ2370-2YA05?

Physical dimensions (181 x 105 x 86 mm) are standard for 3-pole SENTRON MCCBs. The 5SQ2370-2YA05 is a different series; cutout compatibility depends on the panel manufacturer's mounting pattern. Measure the existing cutout against the 105 mm width and 181 mm height before ordering.
