300-line Industry-leading full voltage motor control

The 300-line of NEMA-rated controls offers dependability and long-term  performance for the

most demanding industrial installations. And with all the options available, 

you can match the 300-line to your toughest applications.

Simplicity and durability are key to the 300-line.

The unique design allows for contact inspection or coil change-outs in just seconds, and contact

replacement in a matter of minutes. There’s no need to use tools to remove the starter or

contactor from the enclosure, or to remove control or power wires.

Two options for motor protection

• Three-leg block overload relays feature dual bimetal overload protection and

adjustable ±10% trip current for added flexibility

• Solid-state overload relays provide added motor protection for critical processes,

feature selectable 10/20/30 trip class for application flexibility and surface-mount

technology for increased reliability
