That means the breaker holds its full rating inside a warm panel without a de-rate factor to track. The interrupting ratings climb to 242 kA at 240 V AC and 187 kA at 415 V AC, dropping to 3 kA at 690 V AC — the high short-circuit capacity at the lower voltages suits it for fault-current-heavy installations like transformer secondaries or large busway feeds. ## Trip unit and protection logic It carries an ETU320 electronic trip unit — that's the adjustable thermal-magnetic equivalent in the 3VA platform, giving you LSIG (long-time, short-time, instantaneous, ground-fault) protection curves. The N-conductor protection is configurable to OFF, 50%, or 100% of the phase rating, which matters when you're feeding a panel where the neutral load differs from the phase load. Front-face protection is IP40, so it's suitable for dry indoor panels but not washdown areas. If you need remote signaling or a UVR, you'd look at the -8HL42 or -7HK42 siblings that carry those options.","metaTitle":"Siemens 3VA2010-6HL42-0AA0 SENTRON MCCB, 100 A, 4-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2010-6HL42-0AA0 molded case circuit breaker, 100 A rated current, 4 poles, ETU320 trip unit, 242 kA at 240 V.
