Class 8702 / Refer to Catalog 8502CT9701
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.
