Breaking capacity across voltages
The 3VA1196-4EF36-0AC0: This MCCB delivers 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. That spread covers most low-voltage distribution panels in North America (240/480 V) and Europe (400/690 V).
Thermal derating — what the numbers mean
The 16 A rating holds up to 50 °C ambient. Above that it steps down: 15.36 A at 55 °C, 15.04 A at 60 °C, 14.72 A at 65 °C, 14.4 A at 70 °C. The TM240 release is fixed, not adjustable, so the derating is your only margin.
Panel fit and footprint
The 3VA1196-4EF36-0AC0 measures 76.2 mm wide, 130 mm tall, and 70 mm deep. The 76.2 mm width (roughly 3 inches) is standard for a 3-pole MCCB in this class; it fits alongside other SENTRON 3VA devices in a common distribution block without odd spacing.
