Product details

Its interrupting capacity reaches 220 kA at 240 V, 154 kA at 415 V, and 75.6 kA at 440 V — figures that place it in the high-fault category for industrial distribution and motor control centers where fault currents exceed standard MCCB ratings. 3-pole design, 800 V rated insulation voltage.

At 40 °C the breaker carries the full 200 A; derate to 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C — a straight thermal curve that lets the panel designer size the enclosure ventilation against the load current without guessing.

Undervoltage release and trip unit detail

Factory-fitted undervoltage release (UVR) trips when control voltage drops below threshold.

Frequently asked questions

Will 3VA1220-6MH32-0BA0 drop into a panel specified for a different MCCB?

The 70 mm depth, 105 mm width, and 158 mm height follow the SENTRON 3VA1 footprint. For a panel originally built around a physically different MCCB family, verify bus-bar spacing and mounting hole pattern before ordering.
