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. 430-31)
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.

These tripping characteristics are the mean values of the spread at 20°C ambient temperature
in a cold state.
4
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.
4
Specific characteristics for each individual setting range can be found in MN03402001E.
