CBS ArcSafe, a leading manufacturer of remote racking and switching solutions for low- and medium-voltage switchgear, introduces its remote switch actuator for the ABB/Sace Tmax T7M low-voltage molded case circuit breakers with current ratings of 1000A and 1200A. The new CBS ArcSafe® RSA-174E actuators are designed for Tmax T7M breakers equipped with optional stored-energy mechanisms (SEMs) and allow technicians to safely close and/or trip breakers outside of the arc-flash hazard boundary without any modification to the breaker. In many installations, the Tmax T7M circuit breakers are recessed into a cabinet, and the new remote switch actuators are designed to mount directly on to the breaker inside these cabinets.
When accompanied by a CBS ArcSafe® remote switch operator (RSO) control unit, the RSA-174E reduces the need for arc-flash suits and eliminates all hazardous manual contact with gear during operation by providing open and close operation from up to 300 feet away. The actuator is lightweight, portable, and simple to install and set up, providing technicians with a quick solution for hard-to-access breaker locations. The RSA-174E requires no modifications for switchgear mounting, and operators can easily move the actuator from one breaker to another.
Optional features for the RSA-174E include a radio remote with a range of up to 300 feet, a wired or wireless video camera system with LCD monitor for remote viewing, and a custom-fit rugged storage case. When combined, these features make the RSA-174E easy to install and remove, allowing technicians to quickly and safely set up and operate different sets of the same electrical equipment.
