It carries 50 A continuously at 40 °C, derating to 45 A at 70 °C, so the thermal curve is stable across a typical panel ambient — no surprise drop-off until you push past 55 °C. The interrupting rating hits 220 kA at 240 V AC, which means it can clear a fault at that level without upstream devices needing to coordinate; at 415 V it still holds 154 kA, and at 690 V it drops to 17 kA.
Built-in undervoltage release and auxiliary switch complement
No communication module on this unit; it's a standalone line-protection breaker, not a power-monitoring device.
Panel fit and thermal management
Dimensions are 76.2 mm wide, 130 mm tall, 70 mm deep — a standard 3-pole MCCB footprint that drops into a SENTRON distribution board or a DIN-rail adapter without re-drilling gland plates. Maximum power loss is 17.1 W, so in a sealed enclosure with multiple breakers side by side, factor that into the thermal budget.
