The 300-line three-leg block overload relay includes features that provide positive motor

protection and added operator safety.

±10% adjustment: Relay trip points are factory calibrated for high accuracy. For added flexibility,

the trip current of the relay is adjustable ±10% to allow tuning the protection to any given motor

current and to eliminate nuisance tripping. A single calibration adjusts all three legs. The overload

relay is available in standard or ambient- compensated forms.

The CR324X solid-state overload relay provides added motor protection in critical

production processes where uptime is vital. It mounts directly to 300-line starters, and a

panel-mount version is also available for added application flexibility. Its advanced features can

save you time and money:

• Heaters are eliminated

• Phase loss protection prolongs motor life under adverse conditions

• Solid-state surface-mount technology increases reliability, offers excellent vibration resistance

and reduces heat generation

• Selectable 10/20/30 trip class offers flexibility for a range of applications
