Heaters shown in the table provide a maxi-
mum trip rating of 125% of the motor name-
plate amperes, which is suitable for 40°C
motors. For all other motors select heaters
one code number lower than specified in the
table, which give a maximum trip rating of
approximately 115%.
The tripping current of any heater in a 40°C
ambient is 25% greater than the lower value
of motor amperes shown in the table.
Starters do not provide protection from short
circuits. A protective device should be pro-
vided in accordance with the NEC (CEC in
Canada) and not exceed the values shown in
the table.
Note: If the rating specified is not a standard
size for the circuit breaker manufacturer, use
the next largest size. * Ratings specified are for instantaneous
trip circuit breakers.
Maximum current rating for thermal-
magnetic circuit breakers is 250% of
maximum heater FLA.
Maximum current rating of fuses is:
a. 150% of maximum heater FLA for
Class R, K, or L (time delay).
b. 250% of maximum heater FLA for
Class K or L (non-time delay).
c. 300% of maximum heater FLA for
Class J (non-time delay).
If the calculated rating is between standard
sizes, the next larger size may be used. Fuse
size may not exceed switch size.
Wye-delta starters: If the motor nameplate
shows the full load delta line current only,
divide this value by 1.73 or multiply by .58 to
select the proper heater rating.
Hazardous voltage.
Can cause death, serious person-
al injury, or property damage.
Automatic reset will continue to reset on
two-wire control. When not desired, use
three-wire control.
Do not use manual trip button when relay
is set in automatic reset position.
Fire, electric shock, or explosion hazard.
Can cause death, serious injury or
property damage.
To provide continued protection against risk of fire or
electric shock, examine and if damaged replace cur-
rent-carrying parts and other components of combi-
nation controller. Tripping (opening) of branch-circuit-
protective device may be an indication that fault cur-
rent has been interrupted. If overload relay current
elements burn out, replace complete overload relay.
To maintain overcurrent, short circuit and ground
fault protection, follow manufacturer’s instructions
for selecting current elements and setting instanta-
neous trip circuit breaker.
