2Instruction Leaflet IL16958Effective May 2011For A200 Size 00, 0, 13 Pole Motor ControllerEATON CORPORATION www.eaton.comAUXILIARY CONTACTS - TYPE J (cont.)To remove the unit rotate the retainer screw several times(counterclockwise) and then slide the auxiliary contact unit out ofthe recess.TYPE B OVERLOAD RELAY (See Figure 3)This A200 motor controller is usually equipped with a Type B blocktype ambient compensated overload relay (with gray reset rod). Thecontroller can also be supplied with a non-ambient compensatedoverload relay (with red reset rod). The relay is of the bimetalactuated type equipped with a normally-closed control contact. Anoptional isolated normally-open control circuit is available for fieldmounting. When the overload relay trips, a yellow dot will appearflush with the molded surface below the reset rod. Resetting therelay returns this indicator to its normal concealed position.HEATERSHeaters are not included with the motor controller and must beordered separately per the heater selection table and the informationlisted below. When installing heaters be sure that connectingsurfaces are clean and heaters are attached securely to the relayin the proper location with the screw provided. The trip rating of aheater in a 40°C Ambient is 125% of the minimum fullload currentshown in Table II. When tested at 600 percent of its trip rating, therelay will trip in 20 seconds or less.TYPE A OVERLOAD RELAY (See Figure 4)The A200 motor controller can be equipped with a Type A block typenon-ambient compensated overload relay (unmarked and with redreset rod) or with a block type temperature compensated overloadrelay (marked “ambient compensated” and with gray reset rod). Therelay is of the bimetal actuated type equipped with trip indicator, tripadjustment covering ± 15% of rating and a normally-closed controlcontact. It may be operated with either hand or automatic reset.Reset operation is determined by the position of the plate on theload side of the overload base. Position the reset plate away fromthe panel to set the “hand” position. Loosen the locking screw,move the reset plate toward the panel, and retighten the screw toset the “auto” position.Automatic reset should not be used with 2-wire control circuitswhere automatic starting of the motor may be hazardous.Figure 3.
