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.
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.
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.
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.
