Circuit breakers

Eaton's DS/DSII Circuit Breaker is ideal for metal-enclosed low-voltage switchgear assemblies. It’s a fully interchangeable platform, designed for easy access, easy inspection, reliable protection, and minimal maintenance. The zone-selective interlocking design provides positive system coordination without time delays. Eaton DS/DSII circuit breakers are also equipped with a short time rating, allowing the breaker closest to the fault to trip. Users will appreciate the breaker’s ability to withstand high ratings for maximum selectivity, as well as the built-in safety features that provide optimum operator safety and system security.

Core features

Fully interchangeable so they can be placed into compartments that have the same dimensions and ratings.
Above 240 VAC, breakers have a short time rating equal to the instantaneous rating, which provides for better downstream coordination, allowing the breaker closest to the fault to trip.
Secondary contacts allow more accessories and easy wiring.
Zone selective interlocking provides positive system coordination without time delays.
Microprocessor-based true rms sensing for increased accuracy and reliability.
Built-in safety features (e.g., dead front faceplate shield, padlocking provision, and electrical lockout for manually-operated breakers) provide optimum operator safety and system security.
DE-ION Arc Extinguishers provide superior arc quenching.

Proven technology

Eaton's Types DS and DSL low-voltage air circuit breakers have continually set industry standards for quality, reliability, and extended operating life resulting in the largest installed base of low-voltage power circuit breakers.
