Breaking capacity is 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V — the 690 V figure is the ceiling for this frame, so on 690 V systems the available fault current must be limited to 3 kA or an upstream current-limiting device added. A communication function is built in, allowing integration with higher-level monitoring or control systems without an external adapter module.
Sizing and thermal performance
Maximum power loss is 13.5 W, low enough that adjacent devices in a closed enclosure see minimal heat rise from this breaker alone.
The 105 mm width (4.13 in) matches the typical 3-pole MCCB slot in modular distribution boards, so it drops into existing SENTRON or comparable panel layouts.
