The ETU860 electronic trip unit handles the overcurrent protection curve, and the N-conductor protection is adjustable from OFF through 20 % to 160 % of the rated value. Ground-fault monitoring uses summation current formation on L+N conductors. That footprint fits a standard MCCB cutout in a distribution panelboard; the 4-pole width matches the common 140 mm envelope for this class. Front IP40 protection means it's fine for indoor panel mounting but not washdown environments. Communication function is present, and the breaker includes an other measurement function.","metaTitle":"Siemens 3VA2110-0KQ42-0AA0 SENTRON MCCB, 100 A, 4-Pole, ETU8","metaDescription":"Siemens SENTRON 3VA2110-0KQ42-0AA0 molded case circuit breaker, 100 A continuous, 4-pole, ETU860 release.

The 86 mm depth is also identical.
