Westinghouse DSL416 1600A

The Westinghouse DSL416 1600A is a rugged low‑voltage power air circuit breaker designed for industrial and commercial electrical distribution applications. Built on Westinghouse’s proven DSL family platform, this breaker features a 1600 ampere frame rating and is engineered to protect three‑phase, low‑voltage circuits (typically up to 600 V ac) from overloads, short‑circuits, and electrical faults. The “DSL” designation indicates that this model integrates current limiting features, allowing it to coordinate with current limiters to significantly extend the breaker’s interrupting capacity (up to 200 kA RMS symmetrical with limiters) for demanding systems and high fault current environments.

Typically configured in a 3‑pole, draw‑out design, the DSL416 facilitates ease of installation, preventive maintenance, and serviceability within switchgear assemblies. It can be equipped with a variety of solid‑state trip units (such as Amptector or Digitrip series with LSI functions) to tailor protective characteristics—including long‑time, short‑time, instantaneous and ground fault trips—according to specific load requirements.

The DSL416 is valued for its robust construction, reliable protective performance, and flexibility in system coordination, making it suitable for medium‑ to large‑scale power distribution panels, industrial plants, and commercial electrical infrastructure where dependable interruption of fault currents and adjustable protection settings are essential.
