Heaters for NEMA size 6 and 7 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
Opening of the circuit breaker or power
fuse 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.
