It is built for isolation and switching duty, not overcurrent protection: no overload or short-circuit trip elements inside. The 3VA1110-1AA42-0HH0 uses a front-terminal busbar connection for the main circuit, which means it lands on a busbar stack rather than individual cable lugs — standard for MCCB-style switch disconnectors in distribution panels. The 70 mm depth keeps it within the envelope of most 160 A frame SENTRON breakers, so it shares the same mounting footprint and busbar riser kit. Rated operating voltage is 690 V AC and 600 V DC, with an insulation voltage of 800 V — that gives headroom for 480 V and 600 V class systems without pushing the dielectric limits. The 100 A continuous rating is flat from 40 °C to 70 °C, so a panel that hits 60 °C in summer still carries the full 100 A without needing a larger frame. Mechanical service life is 15,000 operating cycles typical, which is adequate for a switch disconnector used in infrequent isolation service (not daily motor starting). The shunt trip (STL) coil is rated 12–30 V DC / 24 V AC 50/60 Hz — a wide DC range that covers 24 V nominal control supplies with margin. The three CO contacts (two aux + one trip alarm) give the control system discrete feedback for open/closed and tripped states.","metaTitle":"Siemens 3VA1110-1AA42-0HH0 SENTRON Switch Disconnector, 100","metaDescription":"Siemens 3VA1110-1AA42-0HH0 SENTRON switch disconnector, 100 A rated current, 4-pole, 70 mm depth.

The 3VA1110-1AA42-0HH0 is a 4-pole switch disconnector with no overcurrent protection, flat 100 A rating to 70 °C, and includes a shunt trip and three CO contacts. They share the same 70 mm depth and 130 mm height, but the 5ED36-0AC0 is 76.2 mm wide versus 101.6 mm for the 4-pole — so they are not direct drop-in replacements without panel rework."},{"question":"Does 3VA1110-1AA42-0HH0 have UL or IEC compliance documentation?","answer":"The part is designed to IEC 60947 (reference code Q per IEC 81346-2).
