Chapter 6 – Overload Heaters
Heaters for Ther-Mag Circuit Breaker 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.

Circuit breaker tripping 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.
