Its interrupting capacity hits 220 kA at 240 V AC, dropping to 154 kA at 415 V and 121 kA at 440 V — figures that place it in the high-breaking category for large fault-current installations like transformer secondaries or busway feeds. The 100 A rating holds flat from 40 °C through 50 °C, then derates gradually to 91 A at 70 °C — useful if the breaker lives in a warm enclosure or near other heat sources.
Front-face protection is IP40, meaning tools or fingers won't contact live parts, but the sides and base are open to the switchboard environment; no washdown rating here.
Integration notes
Dimensions are 130 mm high, 101.6 mm wide, and 70 mm deep — a standard 4-pole MCCB footprint that drops into most SENTRON distribution panels and third-party switchboards using the same bolt-on or plug-in base. The N-conductor protection is rated at 100 %, meaning the neutral pole carries full rated current without derating, which matters for systems with high harmonic content or non-linear loads. No communication function onboard — this is a straight protection device, not a metering or communicating breaker. If you need remote trip indication or power monitoring, you'll add auxiliary switches or a separate power meter upstream. The motor-drive option (Product Extension / Optional / Motor Drive: Yes) allows remote motorized operation for genset or transfer-switch applications.
