It is explicitly a switch disconnector in MCCB design — not a molded case circuit breaker. There is no overload or short-circuit protection built in; this part is a load-break isolating device, not a protective device. Rated continuous current Iu is 160 A — that is the maximum uninterrupted current the main contacts can carry without exceeding the temperature rise limit. The rated insulation voltage Ui is 800 V, and the maximum operational voltage is 690 V AC 50/60 Hz or 600 V DC. On the DC side, the 600 V rating is the maximum; verify the switching capacity for your specific DC load circuit because DC arc extinction is harder than AC. The UVR coil is designed for 120-127 V AC 50/60 Hz. It does not have a leading contact, so the coil is not self-holding after a dropout — the switch stays open until the coil is manually re-energized. The 4-pole width at 101.6 mm is wider than the 3-pole frame (76.2 mm), so a panel cutout or DIN-rail layout planned for a 3-pole device will need re-spacing. The IP40 front face is standard for panel-mounted switchgear; no additional gland plate sealing is required for the front.","metaTitle":"Siemens 3VA1116-1AA42-0CA0 SENTRON Switch Disconnector, 160","metaDescription":"Siemens SENTRON 3VA1116-1AA42-0CA0 switch disconnector, 160 A rated continuous current, 4-pole, IP40 front.
