Siemens 3VL2716-1AA43-0AA0 Circuit Breaker With Power Switch

Siemens 3VL2716-1AA43-0AA0 is a VL160N four-pole molded-case circuit breaker with an integrated power switch, designed for industrial switchgear that requires a reliable protective device plus local isolation. It is rated for In up to 160 A and a nominal voltage of 415 V AC, with a short-circuit interrupting capacity (Icu) of 55 kA at 415 V, making it suitable for high-current feeders in control panels. This model is supplied without an electronic trip unit and uses box terminals that accept a contact unit and, if needed, an electronic trip unit, enabling straightforward customization within Siemens' VL-series ecosystem. The four-pole configuration provides protection for three-phase circuits plus a neutral, while the built-in power switch enables local isolation for maintenance in 50/60 Hz industrial environments, with typical applications in motor feeders, distribution boards, and industrial control cabinets. The W-power switch variant of this VL160N unit supports local isolation alongside the main protective function, making it a practical choice for panels that require both protection and manual isolation.
