Denton, TX, June 5, 2023 — CBS ArcSafe®, a leading manufacturer of remote racking and switching solutions for low- and medium-voltage switchgear, is pleased to introduce the redesigned RSO-IAR-M18, RSO-IIID-M18, and RSO-IV-M18 remote switch operator (RSO) systems.

Designed for performance and convenience, the new class of RSOs are all powered by Milwaukee M18™ REDLITHIUM rechargeable batteries. They are also lighter weight and offer a simpler interface and more detailed displays and indicators than previous models.

Moving from the legacy lead-acid battery to the M18™ battery gave CBS ArcSafe the opportunity to enhance and upgrade the user experience and functionality. Some of the design features that set the new version apart include:

  • 22% smaller and 40% lighter design than previous RSO versions
  • Enhanced user interface
  • Faster settings input
  • Powered by Milwaukee M18™ REDLITHIUM batteries
  • 5Ah battery included, fits up to 12Ah (Milwaukee M18™ version only)
  • Compatible with all legacy CBS ArcSafe actuators and racking devices
  • A newly designed radio remote with a range up to 300 feet
