Leviton Telcom 277TS-241 Timer Switch 277 Volt

Product Description

The LEVITON TELCOM 277TS-241 is a timer switch designed for 277-volt applications. Timer switches of this type control lighting, ventilation, or other loads on a fixed schedule, automatically opening and closing the circuit at programmed intervals. This unit is sold individually and is typically specified for commercial or industrial electrical installations where 277-volt branch circuits are standard. Licensed electricians install and program this type of device as part of lighting control or energy management systems.

The 277TS-241 is suited for 277-volt single-phase commercial branch circuits commonly found in office buildings, warehouses, retail spaces, and industrial facilities. The part number designation suggests compatibility with 24-hour, 12-hour, and 8-hour timing configurations, making it adaptable to a range of scheduling requirements. Electricians select this switch when a fixed time-based control solution is needed without the complexity of a full building automation system.
