ATC Diversified’s

Overload Relays provide thermal Trip Class 10

overload protection for single and three phase motors, and phase loss

protection for three phase motors. Other features like IP20 guarded

terminals with dual terminal markings, integral stop button, and direct

mounting will help you reduce your total installed costs and enhance the

features and performance of your equipment.

Proven

Our Overload Relays are UL Listed and CE

marked meeting global standards

requirements.

Reliability

Trip Class 10 for reliable and accurate protection against

overload conditions. Trips within 10 seconds when carrying a

current of 720%.

Trip Indication

Visible trip indication to provide clear indication of what

device tripped, simplifies troubleshooting in panels.

Visible Markings

High visibility labels and markings; dual IEC and NEMA

terminal markings for ease of wiring anywhere in the world.

Modular Design

Modular design allows our Overload Relays to be

direct mounted onto CON Series Contactors.

Visible

Certifications

Our product certifications and electrical ratings are clearly

marked on the outside of the devices for easy reference

during installation.

Added Safety

IP20 guarded terminals with dual terminal markings prevent

accidental contact with live parts.
