When your electric motor draws excess power, this 3-pole thermal overload relay from ABB is on hand to take the heat. Once fitted, the unit automatically disconnects the power when the current exceeds 4.2A, preventing damage to the wiring, motor and any connected components. You can adjust the setting between 3.1 and 4.2A, so it has a high degree of compatibility with other motors. In the event of an emergency, you can use the relay's built-in stop function to shut things down speedily.

• Resistant to shock and vibration for reliable performance in harsh conditions
• Power loss per pole of 1.1W for energy-efficient operation
• Broad operating temperature range between -25°C and +60°C to withstand demanding environments
• Automatic or manual reset for versatility

• Construction equipment
• Packaging facilities
• Laboratories
• Conveyor systems

This device measures 45 (W) x 76.7 (H) x 53.5 (D), so it's compact and fits easily into a small enclosure.

It has a 690V AC rated insulation voltage, which makes it suitable for high-voltage applications.
