LPS Series Operations & Maintenance Manual:LPS SERIES SHUNT TRIP DISCONNECT SWITCH
■The Littelfuse LPS series disconnect switch is an integrated power controller designed to meet the requirements of NFPA®70 (National Electrical Code), NFPA 72, ANSI/ASME A17.1 (Safety Code for Elevators and Escalators), NFPA 13 (Installation of Sprinkler Systems) and other state and local jurisdiction requirements with regard to ac power for elevators.
■The Littelfuse LPS series disconnect switch may be ordered in 30 A, 60 A, 100 A, 200 A or 400 A configurations, for 208, 240, 480 or 600 V ac (60 Hz), 3 or 4 wire systems. The Littelfuse LPS series disconnect switch may be configured for use as Service Equipment with the addition of a 2-port ground lug and the appropriate label per NEC Article 230.66 (option S).
■Enclosures are available for the Littelfuse LPS series disconnect switches which meet NEMA 1, NEMA 3R, NEMA 4/4X and NEMA 12 standards.
■The Littelfuse LPS series disconnect switch is designed to interrupt the source of incoming ac power for a single cable or hydraulic elevator, upon a signal from the Fire Alarm Control Panel (FACP). This is primarily to minimize the risk of electric shock, and to prevent impact to the mechanical safety features of an elevator, caused by water released from the fire sprinkler system.
