3 Definite Purpose Contactors and.3 Overload Relay General Overload relays are provided to protect motors, motor control apparatus and motorbranch circuit conductors against excessive heating due to motor overloads and failure to start. This definition does not include: 1) motor circuits over 600 volts, 2) short circuits, 3) ground faults and 4) fire pump control. (NEC Art. 4-31) Time Current Characteristics The time-current characteristics of an overload relay is an expression of performance which defines its operating time at various multiples of its current setting. Tests are run at Underwriters Laboratory (UL) in accordance with NEMA Standards and the NEC. UL requires When tested at 100 percent of its current rating, the overload relay shall trip ultimately When tested at 200 percent of its current rating, the overload relay shall trip in not more than 8 minutes When tested at 600 percent of its current rating, the overload relay shall trip in not more than 10 or 20 seconds, depending on the Class of the relay or heater packs Current Rating is defined as the minimum current at which the relay will trip. Per NEC, an overload must ultimately trip at 125% of FLA (Full Load Amperes) current (heater) setting for a 1.15 service factor motor and 115% FLA for a 1.0 service factor motor. Current Setting is defined as the FLA of the motor and thus the overload heater pack setting. Example: 600% of current rating is defined as 750% (600 x 1.25) of FLA current (heater) setting for a 1.15 service factor motor. A 10 ampere heater setting must trip in 20 seconds or less at 75 amperes motor current for a Class 20 relay. Overload Relay Setting FLA Dial Adjustment For motors having a 1.15 service factor, rotate the FLA adjustment dial to correspond to the motor s FLA rating. Estimate the dial position when the motor FLA falls between two letter values as shown in the example. For motors having a 1.0 service factor, rotate the FLA dial single-half position counterclockwise (CCW). Manual/Automatic Reset The overload relay is factory set at M for manual reset operation. For automatic reset operation, turn the reset adjustment dial to the A position as shown in the illustration. Automatic reset is not intended for two-wire control devices. Test for Trip Indication To test overload relay for trip indication when in manual reset, pull out the blue RESET button. An orange flag will appear indicating that the device has tripped. Push RESET button in to reset.

12 .3 Definite Purpose Contactors and Overload Relays These tripping characteristics are the mean values of the spread at 20 C ambient temperature in a cold state. Tripping time depends on response current. With devices at operating temperature, the tripping time of the overload relay reduces to approximately 25% of the read off value.
