It carries an interrupting capacity of 330 kA at 240 V, dropping to 242 kA at 415 V and 440 V, then 187 kA at 500 V, and 3.7 kA at 690 V. That kind of short-circuit muscle makes it a fit for high-fault panels downstream of large transformers or generator tie-ins — the kind of installation where a fault can dump serious energy before the upstream breaker clears. That simplifies panel layout in a crowded enclosure or a hot nacelle where ambient can climb. The 4-pole design covers three-phase plus neutral switching, common in North American and some IEC distribution schemes. The IP40 front protection means it's sealed against tools and fingers from the front — fine for a closed panel, but it's not rated for washdown. Mount it inside a cabinet, not on the panel face.","metaTitle":"3VA2110-7HN42-0AA0 SENTRON Molded Case Circuit Breaker, 100","metaDescription":"SENTRON 3VA2110-7HN42-0AA0 molded case circuit breaker, 100 A continuous, 4-pole, ETU350 release.

The -7HN42-0AA0 variant omits the voltage trigger and undervoltage release that the -7HK42-0AA0 includes — so if the original design relied on those auxiliary functions, you'd need to add them externally or source the -7HK42-0AA0.
