The Siemens 3VL160X~VL1600 catalog provides specifications, features, and installation information for low‑voltage circuit‑breakers.
The 3VL160X~VL1600 series offers a compact design with a rated current range of 16 A to 1600 A and multiple breaking capacities. The catalog details the four main versions – line protection, motor protection, starter‑combination, and non‑automatic – and describes internal and external accessories such as electronic over‑current releases, auxiliary switches, and terminal covers.
Technical data include IEC compliance, utilization category A, IP protection ratings, and dimensional information. Installation guidance covers both open‑frame and enclosed switchgear applications, with wiring and bus‑bar connection options illustrated in the technical data section.
