It carries a 242 kA breaking capacity at 240 V AC, dropping to 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V — so the interrupting rating you plan for depends on your system voltage. This is a line-protection variant, meaning it's optimized for cable and busbar protection rather than motor or generator protection. It includes a communication function for remote monitoring or trip indication, and a ground-fault monitoring version configured as summation current formation on L+N conductors — useful for detecting leakage on single-phase or three-phase loads without a separate GFCI module.
At 415 V it's still 187 kA, which covers most industrial distribution transformers. The 100 A continuous rating with flat derating to 70 °C means you can load it to nameplate even in a hot panel — no need to downrate for ambient. The communication function enables integration with energy management systems. The ground-fault monitoring uses summation current on L+N. No trip indicator on the breaker face.
