Hubbell's CU300A provides control for multiple voltages in one unit

Hubbell Wiring Device-Kellems introduces the CU300A Universal Control Unit, the lastest addition to Hubbell’s line of Motion Sensing Switches (H-MOSS). The unit provides control for multiple voltages in one unit, eliminating the need to stock more than one unit and simplifying wiring. The CU300A is used to power Hubbell’s ATD, ATP, ATU ceiling and wall mount sensors.

The CU300A Universal Control Unit:

  • Eliminates the need for specialized wiring and automatically detects which voltage is needed – 120V 277V AC, 50/60Hz
  • Features zero arc point switching that minimizes relay contact wear associated with high inrush loads
  • Supplies 24V DC for one to four sensors/AAR combinations
  • Is plenum rated
  • Is UL and cUL certified
