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.
Overload relays with automatic reset may automat-
ically start a motor connected to a two-wire control
circuit. When automatic restarting is not desired,
use a three-wire control circuit.
Circuit breaker tripping may be an indication that
a fault current has been interrupted. To provide
continued protection against fire or shock haz-
ard, 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.
