The distinction matters for a BOM: this part opens and closes a circuit under load but does not trip on overcurrent. It sits in the same 70 mm deep × 76.2 mm wide × 130 mm high footprint as the 3VA1 MCCB siblings, using busbar connection on front terminals for the main circuit. ## Undervoltage release and aux contact complement The UVR has no leading contact, so the main contacts open directly on undervoltage without a time delay. ## Ratings and environmental limits Rated insulation voltage Ui is 800 V; maximum operational voltage is 690 V AC 50/60 Hz and 500 V DC. Short-time withstand is 2 kA at both 1 s and 0.5 s — this is the disconnector's fault-closing and short-time rating, not a breaking capacity. Mechanical endurance is 15 000 cycles. Maximum power loss is 38 W. Front protection is IP40; operating temperature range is -25 °C to +70 °C, storage -40 °C to +80 °C. The unit accepts busbar connection on front terminals, typical for panel-mount distribution. Lifecycle status is listed as current production. This is an active catalog line within the Siemens SENTRON 3VA family.","metaTitle":"Siemens 3VA1116-1AA32-0CH0 SENTRON Switch Disconnector, 160","metaDescription":"Siemens 3VA1116-1AA32-0CH0 SENTRON switch disconnector, 160 A rated continuous current, 3-pole, IP40 front, with undervoltage release 120-127V AC.
