Heaters for Mag-Break
®
Controllers
The Mag-Break protector is factory adjusted to the
minimum trip setting.
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.
Use the heater table to verify that the Mag-Break and
current limiter rating is correct for the motor full-load
current. Then set the Mag-Break trip setting to the
recommended value.
If the Mag-Break trips during motor startup, increase
the trip setting by one step at a time until the motor
can be consistently started. Do not exceed the maximum
trip setting shown in the heater table.
Overload relay tripping current in 40° C ambient is the
minimum value of heater full-load current multiplied
by 1.25.
Size 0 and 1 (Standard )
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.
To maintain overload, short-circuit, and ground-
fault protection, use the following instructions
to select heaters and to adjust the Mag-Break
trip setting.
