Reclosers Automatic circuit reclosers are recognized by electric utilities throughout the world as an essential device for achieving their prime goal: providing maximum continuity of electric service to their customers simply and economically.

Single-phase reclosers are used to protect single-phase lines such as branches or taps of a three-phase feeder. They can also be used on three-phase circuits where the load is predominantly single phase. Thus, when a permanent phase-to-ground faul

 There are various types of three-phase reclosers available to satisfy multiple applications at the most economical cost. They are used as main breakers three phase feeders for substations with rating up to 1200 amps and 20 KA and also for di

 The intelligence that enables a recloser to sense overcurrents, select timing operation, time the tripping and reclosing functions, and finally lockout is provided by the recloser control. There are two basic types of control schemes used: a

Hydraulic recloser control is used in most single-phase reclosers and in three-phase recloser types 6H and V6H. It is built as an integral part of the recloser. With this type of control, an overcurrent is sensed by a trip coil that is connected i

Kyle electronic recloser controls are used in most three-phase reclosers and in the single-phase recloser types VXE and NOVA1. Compared with the hydraulic control, they are more flexible, more easily customized and programmed, and many have advanc

 The sectionalizer is a self-contained, circuit-opening device used in conjunction with source-side protective devices, such as reclosers or circuit breakers, to automatically isolate faulted sections of electrical distribution systems. Power

Single-phase sectionalizers are used to protect single-phase lines such as branches or taps of a three-phase feeder. They primarily are installed beyond single-phase reclosers to isolate the fault to the smallest area. They will not require refusi

There are various types of three-phase sectionalizers available to satisfy multiple applications at the most economical cost. They are used to segment distribution feeders into multiple zones of protection. Three-phase sectionalizers are applied w
