Rab LOS800W/277 Wall Occupancy Sensor 277V White

Product Description

The RAB LOS800W/277 is a wall-mounted occupancy sensor designed to automatically control lighting loads based on detected occupancy. Operating at 277 volts, this sensor is suited for commercial and industrial lighting control applications where line-voltage switching is required. The unit mounts in a standard wall box and is finished in white to blend with common electrical hardware. Licensed electricians install this device as part of an energy-management or lighting control system, replacing manual switches in spaces that benefit from automated on/off control.

The LOS800W/277 is intended for wall-switch applications in commercial environments such as offices, restrooms, conference rooms, storage areas, and similar spaces. Its 277-volt rating makes it compatible with standard commercial fluorescent and LED lighting circuits fed from 277V branch circuits common in commercial electrical distribution systems. It is not intended for residential low-voltage or dimming applications.

Key Features

• 277-volt operating voltage suitable for commercial lighting branch circuits
• Wall-mount form factor fits standard single-gang electrical boxes
• White finish compatible with standard commercial wallplates
• Occupancy-based switching reduces energy use by turning lights off in unoccupied spaces
• Line-voltage design eliminates need for separate low-voltage control wiring

Compatibility

Designed as an OEM-style replacement or new-installation wall occupancy sensor for 277-volt commercial lighting control circuits.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit at the breaker panel and verify absence of voltage with a meter before beginning any wiring work. The sensor mounts in a standard single-gang wall box; follow manufacturer wiring diagrams for line, load, and neutral connections. Do not install on circuits outside the rated voltage range.
