The front terminal and busbar connection pattern (width 101.6 mm, depth 70 mm, height 130 mm) fits the standard 4-pole MCCB footprint; it mounts on a DIN rail or panel baseplate and accepts busbar links for common feed distribution. Maximum power loss is 38 W at rated current, which is modest for a 100 A 4-pole device — the heat it dumps into the enclosure is predictable and low enough to avoid forced ventilation in most standard panels. Mechanical service life is 15 000 operating cycles typical — this is a switch-disconnector rated for frequent manual operation on a production line, not a daily-use contactor, but 15k cycles covers years of normal isolation duty. ## What it does and does not include No overload or short-circuit protection is built in; upstream protection must be provided by a separate circuit breaker or fuse. A motor drive is available as an optional extension (product extension optional: yes), so the switch can be motorized for remote or automatic isolation if needed — the base unit ships without it.","metaTitle":"Siemens 3VA1110-1AA42-0AA0 SENTRON Switch Disconnector, 100","metaDescription":"Siemens SENTRON 3VA1110-1AA42-0AA0 switch disconnector, 100 A rated current (flat to 70 °C), 4-pole, 690 V AC / 600 V DC.
