Its breaking capacity is 187 kA at 240 V AC, dropping to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 3.7 kA at 690 V — the high 187 kA figure at 240 V makes it suitable for installation close to large transformers or high-fault-capacity utility feeds where upstream fault current can exceed 100 kA.
Integration — Dimensions, Auxiliaries, and Panel Fit
The basic switch assembly carries order code 3VA21635HL360AA0, which is the replaceable switching mechanism inside the molded case — useful to know if the breaker trips frequently under fault and the contacts need swapping rather than replacing the whole unit. Maximum power loss is 4 W, which is low enough that no forced cooling is needed in a standard IP40 enclosure, but the designer should still account for it in the thermal budget if multiple breakers are ganged.
Temperature Range and Storage
The 70 °C operating max matches the continuous current rating, so the breaker can be installed in a hot machine cabinet or near a furnace without derating.
