General Information

Class 8702 Type S reversing magnetic contactors are used for starting, stopping, and reversing AC motors where overload protection is separately provided. Class 8702 reversing contactors consist of two Class 8502 contactors mechanically and electrically interlocked. Open type devices, Sizes 0–5, are available in either horizontal or vertical arrangements. Sizes 00 and 6 are available as horizontal only. Enclosed devices, Size 00–6, use horizontally arranged components. Type S reversing contactors are designed for operation at up to 600 Vac, 50/60 Hz. NOTE: In Table 16.159, replace the three bullets (●●●) in the catalog number with the coil voltage code. Refer to the standard coil voltage codes listed in Table 16.160. For information on field modification of NEMA 12 enclosures, see page 16-113 .

[1] NEMA 4X stainless steel enclosures (sizes 0–5) have a brushed finish. [2] NEMA 4X stainless steel enclosures are shipped with hubs installed in the top and bottom of the enclosure. [3] NEMA 12 enclosures can be field modified for outdoor non-corrosive and non-service entrance rated applications. See Enclosures—Reversing, page for more information. [4] 24 V coils are not available on Sizes 4-6. On Sizes 00-3, where 24 V coils are available, FormS (separate control) can be specified (i.e., order as 8702SAO4V01S). [5] This voltage code can include FormS for separate control (provided at no charge) (for example, order as 8702SAO4V02S).
