This is a pure disconnector — no overload or short-circuit protection — intended for manual isolation and safety lockout where the upstream breaker or fuse provides the overcurrent protection. ## Undervoltage release and connection details Connection is via front terminals (clamp type) for the main circuit, with no auxiliary contacts or communication function on this variant. An optional motor drive can be added for remote switching, though the base unit is manually operated. ## Dimensions, mounting, and environmental limits At 70 mm deep, 76.2 mm wide, and 130 mm tall, this disconnector fits the standard MCCB footprint for 160 A frame size — it occupies three pole widths on a DIN rail or panel-mount base. Front protection is IP40, suitable for enclosed panel mounting where no water ingress is expected; the operating temperature range is -25 °C to 70 °C, with storage from -40 °C to 80 °C.","metaTitle":"Siemens 3VA1110-1AA36-0BA0 SENTRON Switch Disconnector, 100","metaDescription":"Siemens SENTRON 3VA1110-1AA36-0BA0 switch disconnector, 100 A, 3-pole, in MCCB design.
