SIRIUS 3RV2 Circuit Breakers

SIRIUS 3RV2 circuit breakers protect motors by isolating feeders during short-circuit, overcurrent, or phase loss, with lockout, spring terminals, UL 3RV27/28.

You need maximum machine and plant availability to achieve peak productivity. The SIRIUS 3RV2 motor starter protector delivers 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 raw materials with recycled organic waste— delivering the same quality and performance you demand allowing you to achieve your sustainability goals without compromising performance.

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

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

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

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

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