The 3VA1196-5EF32-0AF0: The TM240 thermal-magnetic overcurrent release means the thermal element is fixed at 16 A (non-adjustable), with a magnetic trip threshold factory-set to 240 A — 15× the rated current, so it clears high-impedance faults fast while riding through motor inrush on the same feeder.
Breaking capacity — the real-world fault clearing
This MCCB carries 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V.
Thermal derating — don't lose capacity in a warm panel
At 55 °C it derates to 15.36 A, at 60 °C to 15.04 A, at 65 °C to 14.72 A, and at 70 °C to 14.4 A. In a tightly packed panel near the top of a switchboard where ambient can hit 55–60 °C, the derated value governs the actual load you can feed — plan the branch circuit for 15 A continuous if the enclosure runs hot.
The 3VA1196-5EF32-0AF0 measures 70 mm deep, 76.2 mm wide, and 130 mm high — the standard 3VA frame footprint for 3-pole breakers up to 160 A. No undervoltage release or shunt trip is fitted from the factory; those can be added as field-installable accessories.
