Westinghouse
A200 Overload Relay Heater Elements for Motor Protection
Westinghouse A200 overload heater elements
can be identified by the catalog number on one terminal. Heater selection
should be based on the full load current and service factor which is listed on
the motor nameplate.
If the motor and overload relay are in the
same ambient, and the service factor of the motor is 1.15 to 1.25, pick heaters
from the table below. If the motor service factor is 1.0 or a maximum of 115%
protection is wanted, pick one size smaller heater than indicated.
