This is a pure disconnect — no overload protection, no short-circuit protection. It's a load-break switch for isolation and manual switching, not a circuit breaker. The 3-pole version handles three-phase loads up to 690 V AC or 500 V DC. An optional motor drive can be added for remote operation. That means no derating curve to calculate — if your load pulls 100 A, this switch handles it at 70 °C ambient without a second thought. Max power dissipation is 38 W, so plan for that heat in the enclosure. Mechanical service life is 15,000 operating cycles typical. The front terminals accept busbar connections, and the nut keeper kit simplifies panel mounting. It's designed for a SENTRON distribution board or a standalone enclosure. The IP40 front protection means it's suited for indoor panel installation where dust ingress is limited. No special sealing gaskets needed for a standard IP40 enclosure.","metaTitle":"Siemens 3VA1110-1AA32-0AF0 SENTRON Switch Disconnector, 100A","metaDescription":"Siemens 3VA1110-1AA32-0AF0 SENTRON switch disconnector, 3-pole, 100A rated current flat to 70°C, 690V AC.
