Features

The features include: disconnect switch and circuit breaker versions; rugged flange mounted handle; easy installation; occupation of less space; increased operator protection; room to spare for modifications; Class R fuse clips standard; electrically and mechanically held; 30–600 A. It is desirable to install the branch-circuit protective device and lighting contactor, combining switching and over-current protection, in one enclosure. Combination lighting contactors are well suited for industrial, highway and area lighting applications, or where a lighting circuit may have to be disconnected for periodic maintenance. They may also be used for resistance heating loads. Table 16.200: Fusible or Non-Fusible Disconnect Switch—3-Pole, 50–60 Hz (replace ●●● with the voltage code)

For How to Order Information, see page page 16-28.

[21] For NEMA 4 and 4X watertight, dusttight ,and corrosion-resistant glass-polyester enclosures, add FormG18 (limited to 100 A max.). 400 and 600 A enclosures are painted sheet steel (NEMA Type 4 & 4X). [22] NEMA 12 enclosures can be field modified for outdoor non-corrosive and non–service entrance rated applications. See page 16-113 for more information. [23] Replace the three bullets (●●●) in the catalog number with the coil voltage code. Refer to the standard voltage codes shown in Table 16.197. [24] The control/coil voltage must be specified. [25] 24 V coils are not available for 200 A or larger devices. Contact the Customer Care Center for additional information.
