It is built to the IEC frame 160 standard and serves as a manual load-break disconnect, not a protective device: it has no overload or short-circuit protection elements. The part carries a shunt trip (STL) release rated 110–127 V DC and AC 50/60 Hz, plus a complement of 2 auxiliary switches and 1 trip alarm switch (HQ design). The shunt trip operates on 110–127 V DC or AC 50/60 Hz; verify control voltage matches your trip circuit before specifying. The front terminal arrangement accepts busbar connection, typical for panel feed-through or distribution blocks. ## Integration notes — panel and wiring The 3VA1 frame mounts with a nut keeper kit (included per the description). Dimensions: 70 mm depth, 101.6 mm width, 130 mm height — fits standard MCCB cutouts in switchgear panels. Mechanical service life is 15 000 operating cycles typical. The auxiliary switch complement (2 CO + 1 trip alarm) provides status feedback for PLC or indication lamps without adding external relay blocks.","metaTitle":"3VA1110-1AA42-0JH0 SENTRON Switch Disconnector, 100 A, 4-Pol","metaDescription":"SENTRON 3VA1110-1AA42-0JH0 switch disconnector in MCCB design. 100 A continuous, 690 V AC / 600 V DC, 4-pole with shunt trip (STL) 110-127 V AC/DC.
