The Siemens 3VA1116-1AA46-0AA0 is a SENTRON switch disconnector in an MCCB-style housing — 4-pole, rated 160 A continuous at 40 °C, with a 690 V AC / 600 V DC operating voltage ceiling and an 800 V rated insulation voltage. It is designed for load-break isolation without overload or short-circuit protection (no trip unit, no undervoltage release, no auxiliary contacts). The front-terminal clamp connection and IP40 front face suit panel-mount distribution boards where a visible-break disconnect is required ahead of downstream protection.
Current rating across temperature — the real working limit
Above that, the thermal derating is gradual: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C.
Dimensions: 130 mm height, 101.6 mm width, 70 mm depth. The front terminal arrangement and clamp connection accept copper or aluminium conductors. Maximum power dissipation is 38 W at rated load.
Mechanical endurance and optional motor drive
Typical mechanical service life is 15,000 operating cycles. The product accepts an optional motor drive (field-installable) for remote switching, though no communication function is built in. No auxiliary contacts or releases are included on this variant.
