SIRIUS 3RV2 Circuit Breakers

Why SIRIUS 3RV2 circuit breakers?

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.

Key benefits

Isolate faulty load systems

In the event of a short-circuit (current >13 times the rated current), the short-circuit releases isolate the faulty load feeder from the power supply within milliseconds.

Prevent system damage

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.

Cover all protection needs with one product line

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.

Featured capabilities

Integrated lockout/tagout mechanism

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

Simple installation

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.

Optional door coupling

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.
