NEMA FULL VOLTAGE POWER DEVICES, CONTROL SECTION 1

1-26

— CR309 magnetic starters Two-speed, one-winding (consequent pole), 5-3 pole Non-combination, open, NEMA type 1, 3R, 12, 4/4X NEMA sizes 0-5 with thermal overload relay 600 volts maximum 50/60 hertz

Three-phase Includes a holding interlock, mechanical and cross-electrical interlock, pressure terminals for the line and load connections, plus a 3-leg block type overload relay (manual reset) for each speed. All enclosures include external reset. One NO isolated contact on each overload relay is available as an option (for both). To order, change suffix AEA to LEA for Product Numbers listed in table. Six heaters should be ordered as separate items. See pages 1-153 to 1-159 for selection. Starters are wired for constant or variable torque motor application. Reconnection of control wiring may be required for constant horsepower application. Motor full-load current should not exceed continuous ampere rating of starter. Refer to Coil Table, page 1-6, for other available coils including 50 Hertz.
