It provides visible isolation and load-break capability without integral overload or short-circuit protection — it is a disconnector, not a circuit breaker. Rated operational voltage reaches 690 V AC 50/60 Hz and 600 V DC, with an insulation voltage (Ui) of 800 V. ## Auxiliary contacts and integration The auxiliary release is omitted — no shunt trip or undervoltage release is fitted, so remote tripping requires an external motor drive (optional, per the product extension listing).","metaTitle":"Siemens 3VA1110-1AA42-0AG0 SENTRON Switch Disconnector, 100","metaDescription":"Siemens 3VA1110-1AA42-0AG0 SENTRON switch disconnector, 100 A rated continuous current, 4-pole, IEC frame 160, IP40 front.
