ACW Molded Case Circuit Breakers - High Breaking Capacity (UL)

Available in two levels of short-circuit interrupting capacity (35 & 65kA @ 480Vac),the ACW Series assures top performance from 15 to 800Amps.Common plug-in accessories simplify field installation and minimize inventory.

Introducing the WEG ACW Series of Molded Case Circuit Breakers now available with UL489 certification.Available in four different compact frames, the New ACW Series will assure top performance for power distribution on both thermal and short-circuit protection from 15 to 800Amps.

Its robust desing and double contacts structure optmize performance and increase breaking capacity (kA rms). The ACW series is available in two levels of short-circuit interrupting capacity – standard industrial & commercial applications (35kA), as well as required in high-performance applications (65kA). Common plug-in accessories simplify field installation and minimize inventory variations on distributors’ shelves.

Air Circuit-Breaker ABW

Ideal for the protection of high power low-voltage electrical circuits. Rated operational currents up to 6300A and high short-circuit breaking capacity. Available with 3 or 4 poles for both versions:fixed or withdrawable

Circuit breakers are devices used to protect electrical circuits and related equipments from overload and short-circuit overcurrents. It is imperative to choose and size circuit breakers according to each specific application, and level of protection imposed by safety requirements.

WEG series of Air Circuit Breakers offers high breaking capacity to protect low voltage applications in high power circuits. Its modular design is enhanced by only four different frame sizes to best suit most applications.
