It's rated 160 A continuous at 40 °C and holds that rating flat through 50 °C, then derates to 150 A at 70 °C. That's a solid thermal curve for a warm panel; you don't lose headroom until the ambient pushes past 50 °C. Interrupting capacity is where this part earns its keep: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. That's a high-interrupting MCCB — it handles fault currents that would weld a standard 25 kA breaker shut. For a 480 V panel with a large transformer upstream, this gives you the SCCR headroom without cascading upstream fuses.
Panel fit and footprint
Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a compact 3-pole MCCB that fits standard distribution panelboards. The 76.2 mm width (3 inches) is the standard 3-pole MCCB pitch; it'll drop into existing SENTRON or older 3VL panel cutouts without re-drilling the mounting plate.
