SIRIUS 3RV2 Circuit Breakers

SIRIUS 3RV2 circuit breakers protect motors by isolating feeders during short circuits, overcurrents, or phase loss, featuring lockout and spring terminals, UL 3RV27/28.

You need maximum machine and equipment availability to achieve peak productivity. The SIRIUS 3RV2 motor starter protector provides ideal protection by quickly disconnecting your equipment from the power supply when overloads occur—preventing costly damage and keeping your operations running smoothly.

SIRIUS 3RV2 circuit breakers feature housings made from exceptionally sustainable plastic that replaces all fossil-based raw materials with recycled organic waste—delivering the same quality and performance you expect, allowing you to achieve your sustainability goals without compromising performance.

Protect your systems with an overload release based on a specific time-current characteristic. Easily perform repairs thanks to a motor starter protector with a lockable operating mechanism for manual closing and opening.

Available in sizes S00, S0, S2, and S3, as well as in different versions, our motor starter protectors and circuit breakers cover all aspects of protecting motors, starters, transformers, and UL 489 applications.

The standard lockable operating mechanism on every SIRIUS 3RV2 device prevents unauthorized access and enables safe maintenance procedures in accordance with lockout/tagout protocols.

Screw and spring-type terminals for sizes S00 and S0 up to 40 A enable quick assembly. Link modules provide a fast connection to SIRIUS switching devices for streamlined system integration.

Door-coupling mechanisms can be installed in a control cabinet and operated from the outside. When the cabinet door is closed, the operating mechanism is engaged and locked, which prevents the door from being opened unintentionally.
