At 415 V it still breaks 75.6 kA, and at 690 V it holds 11.9 kA — the SCCR curve drops with voltage, so verify the available fault current at your system voltage.
Maximum power loss is 21.7 W, so account for that heat when sizing the cabinet's thermal budget. Dimensions are 70 mm deep, 76.2 mm wide, and 130 mm tall — a standard 3-pole MCCB footprint that drops into most SENTRON panelboards and distribution blocks without re-drilling the mounting plate.
This part is sourced to order against an RFQ through independent distribution. Submit an RFQ for current pricing and availability confirmation.
The maximum breaking capacity at 240 V is 121 kA. At 415 V it is 75.6 kA, at 440 V it is 52.5 kA, and at 500 V and 690 V it is 11.9 kA.
