Project Description

Recloser Control Products

Recloser controls are the front line of the distribution power system, often located in distribution substations or on feeders, recloser controls supply the intelligence to allow reconfiguration of distribution systems and maintain reliable service to as many people as possible in the event of a fault.
SEL offers a range of recloser controls to fit the needs of any system from basic three phase reclosing to advanced loop schemes, communication assisted tripping, and single pole tripping.
