Overload Heaters for Fused Controllers
For continuous-rated motors with a service factor of
1.15 to 1.25, select the appropriate heaters for the
motor full-load current. For continuous-rated motors
with a service factor of 1.0, multiply the motor full-load
current by 0.9 and use this value to select heaters.
Overload relay tripping current in 40° C ambient is the
minimum value of full-load current multiplied by 1.25.
Provide short-circuit protection in accordance with the
National Electrical Code, except that fuses are not to
exceed the value shown in the table.
Suitable for use in a circuit capable of delivering not
more than the maximum RMS symmetrical amperes
indicated in the Maximum Fuse and Short-Circuit
Rating table below, 600 V maximum, when protected
by an appropriate fuse having an interrupting rating
not less than the available short-circuit current.

Opening of the fuse(s) may be an indication that
a fault current has been interrupted. To provide
continued protection against fire or shock hazard,
examine all current-carrying parts and other
components of the motor controller and replace any
damaged components. If heater burnout occurs,
the complete overload relay must be replaced.
Overload relays with automatic reset may auto-
matically start a motor connected to a two-wire
control circuit. When automatic restarting is not
desired, use a three-wire control circuit.
