CBS ArcSafe Introduces RSA-134H for Square D Type QMB Safelex


CBS ArcSafe® introduces its remote switch actuator (RSA) for the Square D Type QMB Safelex 2000 A panelboard switch (PBS). The lightweight, portable CBS ArcSafe RSA-134H allows technicians to remotely close or trip a Square D PBS from a safe distance of up to 300 feet, well outside the arc-flash boundary.

Installation and operation do not require any modifications to existing electrical equipment, thanks to CBS ArcSafe’s magnetic latching system. Typical applications include switching and protection of low-voltage AC and DC power distribution systems. When compared to other arc-flash mitigation alternatives, the RSA-134H is a cost-effective solution for keeping operators safe when using Square D QMB Safelex 2000 A switches.

Optional features include a radio remote with a range up to 300 feet, a 24 V DC LED light, a wireless video camera system with an LCD monitor, and a rugged protective case assembly. All RSA units are portable with fast and easy setup. They offer mechanical and/or electrical safety protection, are adjustable to fit unique electrical equipment configurations, reduce requirements for personal protection equipment, and meet NFPA 70E arc-flash safety compliance standards.
