Its breaking capacity scales with system voltage: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 690 V. The thermal derating is minimal up to 50 °C (full 63 A), then drops to 60.48 A at 55 °C and 56.7 A at 70 °C, so a panel ambient above 50 °C requires a de-rate check against the connected load. This means the breaker can signal its status and trip condition back to a PLC or control system without an add-on module.
Integration and deployment context
Dimensions are 130 mm height, 76.2 mm width, and 70 mm depth — a standard 3-pole MCCB footprint that fits most SENTRON panelboards. The latching endurance is rated at 15,000 cycles, which governs mechanical life in frequent-switching applications.
