The 160 A rating holds continuously at 40 °C ambient and derates to 150 A at 70 °C, per the thermal curve. At 240 V this breaker clears 220 kA; at 415 V it's 154 kA; at 440 V it drops to 75.6 kA; at 500 V and 690 V it holds at 17 kA. That 220 kA figure at 240 V is well above typical utility fault levels in North American 240/120 V split-phase or 240 V delta services — it gives headroom for high-fault locations like substation secondaries.
Integration — panel fit and mounting
The 3VA1116-6GD42-0AA0 measures 130 mm high, 101.6 mm wide, and 70 mm deep. The 4-pole width of 101.6 mm (4 inches) is the standard 4-pole MCCB footprint for this frame class — it occupies four 25.4 mm (1-inch) module positions on a DIN rail or panel-mount plate. The 70 mm depth leaves clearance for rear-mounted busbars or a gland plate; verify the enclosure depth against that dimension plus wiring space. For a 4-pole breaker in a sealed enclosure, that 38 W contributes to the internal temperature rise.
