TYPEN HEATERELEMENTS
HEATER
ELEMENT
SELECTION
- The “Full Load Amps.” listed in
the tables are to be used for heater element selection. The
rating of the relay in amperes at 40” C is 115% of the “Full Load
Amps.” listed for the “Heater Type No.”
Refer to the motor nameplate for the full load current, the
service factor, and/or the motor classification
by application
and temperature rise.
Use this motor nameplate information, the application rules,
and the “Full Load Amps.” listed in the proper table (see Index
on Page 2) to determine the “Heater Type No.”
OVERLOAD
RELAY CLASS DESIGNATIONS
- Industry standards
(NEMA Part ICS 2-222) designate an overload relay by a class
number indicating the maximum time in seconds at which it will
trip when carrying a current equal to 600 percent of its current
rating.

Specific Applications
may require Class 10 or Class 30
overload relays. Class 10 overload relays are often used with
hermetic motors, submersible
pumps, or motors with short
locked rotor time capability. Class30 overload relaysshould be
used with motors driving high inertia loads where additional
accelerating time is needed.
For application
regarding Class 10 and 30 overload
consult local Allen-Bradley
office.
relays,
OF NOT LESS THAN 1.15, OR
RISE NOT OVER 40°C.
- If the
at the Controller than at the Motor
full load current value shown on the motor nameplate is
between the listed “Full Load Amps.“, select the “Heater
Type No.” with the higher value. This will provide integral
horsepower motors with protection between 115 and 125%
of the nameplate full load currents.
2. Higher Temperature
3. Lower Temperature
- If the
at the Controller than at the Motor
full load current value shown on the motor nameplate is
between the listed “Full Load Amps.“, select the “Heater
Type No.” with the lower value. This will provide integral
horsepower motors with protection between 105 and 115%
of the nameplate full load currents.
A Class 30 overload relay will trip in 30 seconds or less at a
current equal to 600 percent of its rating.

either Type N or W heater elements provide Class 20 operation
and are recommended
for General Application.
DUTY:
1. The Same Temperature
at the Controller and the Motor - Select
the “Heater Type No.” with the listed “Full Load Amps.”
nearest the full load value shown on the motor nameplate.
This will provide integral horsepower motors with protection between 110 and 120% of the nameplate full load
currents.
A Class 10 overload relay will trip in 10 seconds or less at a
current equal to 600 percent of its rating.
A Class 20 overload relay will trip in 20 seconds or less at a
current equal to 600 percent of its rating.
