Rated insulation voltage is 800 V, and the interrupting capacity reaches 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V. The unit includes a communication function, allowing remote monitoring of breaker status via the SENTRON powerconfig software. Front-side protection is IP40.
The ETU550 trip unit is a common variant, making this breaker a stable line-item for new panel designs or replacement of older 3WL or 3VF series breakers in retrofit applications.
The breaker measures 181 mm high, 140 mm wide, and 86 mm deep — a standard 4-pole MCCB footprint for the 100 A frame size. It mounts via four screws to a backplate or DIN-rail adapter (the 3VA series uses a screw-fixed base; a DIN-rail mounting plate is available as an accessory). Verify the 140 mm width against your existing busbar or cable-ladder spacing before ordering. Power dissipation at rated current is 7.7 W maximum — negligible for panel thermal calculations in a ventilated enclosure, but worth noting if the breaker is in a sealed, high-density cabinet with multiple devices.
