MCCB with real interrupting muscle
It packs a 187 kA interrupting capacity at 240 V, dropping to 121 kA at 415 V and 440 V, then 79 kA at 500 V, and 4.25 kA at 690 V — that's real fault-clearing power for high-available-current plant feeders or transformer secondaries. Power loss tops out at 28 W, so heat management in a packed panel is manageable.
The 86 mm depth means it clears shallow enclosures where deeper breakers won't fit. It ships with a basic switch (3VA2116-5HL32-0AA0) and an integrated auxiliary trip (3VA9608-0BB11) for remote status and shunt-trip capability.
The thermal derating curve is flat from 40 °C to 50 °C at 160 A, then steps down: 154 A at 55 °C, 148 A at 60 °C, 142 A at 65 °C, and 136 A at 70 °C. Latching endurance is 20,000 operations.
