ABB 20 → 25 A MS Range Motor Protection Circuit Breaker, 690 V

Want to make sure electrical faults can't make it to your machinery? Put up a shield in the shape of this motor protection circuit breaker from ABB. It provides automatic protection from overloads, phase failures and short circuits. You can also manually turn the connected motor on or off by rotating the unit's switch. For user safety, a disconnect function lets you safely isolate the motor during maintenance or configuration changes. Thanks to a rated operational voltage of 690V AC, this is a suitable choice for medium-voltage applications.

• Current rating between 20 and 25A for low-power to medium-power motors
• Compact dimensions of 45 (W) x 97.8 (L) x 86.6mm (D) make it ideal for installation where space is tight
• Fuseless component cuts down on maintenance
• Phase loss sensitivity to enhance protection and avoid downtime

• Engineering workshops
• Industrial automation
• Production lines

It has a trip class of 10A, meaning it cuts power to a motor between 2 and 10 seconds after an abnormal load is detected. This short delay allows the motor to come safely to a halt.
