ABB 300-line Industry-leading full voltage motor control

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.

Simplicity in design

The right control for your application every time

A wide range of choices

• Non-reversing, reversing, two-speed and combination motor starters in sizes 00–6

• NEMA Type 1. 3R, 12. 4 and 4X enclosures available

• Save time and money with a single source for all your applications

Versatile, durable and the industry’s easiest to maintain

• Change the coil voltage on a contactor or starter to suit your application

• Inspect and change out contacts without removing any wires, or removing the

starter from the enclosure

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

Largest selection of modification and accessory kits

• Cost-effective solutions

• Allows for application and configuration flexibility

• Kits include auxiliary contacts, coils, surge-suppression, fifth-pole, mechanical  interlocks,

control circuit fusing, NEMA type enclosures, selector switches, indicating lights, control

transformers, space heaters and more
