Siemens 3KA53301GE01 Switch Disconnector

Siemens 3KA53301GE01 Switch Disconnector is a 3‑pole low‑voltage isolation switch from Siemens’ 3KA family, designed to provide a reliable isolation point within switchgear. It handles a continuous current of 160 A (IU) and an operating voltage of up to 690 V (UE) across three phase lines, and it includes a door‑drive mechanism (8UC7) for straightforward panel mounting and operation. The enclosure features a light gray basic masking frame with a grey/blue‑green handle, reflecting its new‑design aesthetics and built‑in accessibility. Rated for AC‑22 B utilization at 500 V, it also offers a short‑circuit current rating up to 120 kA, enabling safe interruption under fault conditions. Typical applications include service isolation for feeders in industrial control panels, machine builders’ LV switchboards, and other distribution boards where a dedicated isolation point is required, integrating seamlessly into Siemens low‑voltage switchgear architectures. 3KA53301GE01 is commonly referenced with the 3KA5330‑1GE01 designation, reflecting slight nomenclature variations while describing the same device and specifications.
