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.
Overload relays with automatic reset may
automatically start a motor connected to a two-wire
control circuit. When automatic restarting is not
desired, use a three-wire control circuit.
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 Rat-
ing 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.
