OSM_Al_2 Series RecloserThree-Phase Recloser System (Three-Phase Trip)

Tavrida Electric is a world-class manufacturer of vacuum interrupters, magnetic actuators, circuit breaker modules and automatic circuit reclosers. The OSM Series is a field proven, reliable and flexible system that can be used as a switch, circuit breaker, substation breaker, sectionalizer or distribution recloser. With over 55,000 installations worldwide, the OSM Series has demonstrated unrivalled dependability in the most extreme environments.

The OSM Series Recloser is fully compatible with any MRI type (Multi-Recloser Interface) control: SER-651R, Beckwith M7679. The six (6) on-board voltage sensors allow the OSM Series Recloser to be installed in either a radial or loop scheme configuration. Radial installations can be quickly changed to a loop scheme configuration by simply reprogramming the SEL-651R control.

Recloser components

Other components

OSM_Al_2 Series Recloser

Outdoor Switching ModuleThe Outdoor Switching Module (OSM) is designed for use as an automatic circuit recloser, a sectionalizer on overhead distribution lines, and as an outdoor switching module in distribution substation applications for voltages up to 27 kV.

Recloser controlThe Tavrida OSM recloser is compatible with SEL, Beckwith Electric and a variety of other controls.

Umbilical cableConnection between the OSM and the control cabinet is accomplished by a single umbilical cable which can be provided in any required length.

Mounting kitTavrida Electric offers several mounting options including pole or substation frame mounting. Pole mounted reclosers are fitted with all requested options in a single lift package, and can also be installed in line or rotated 90 degrees.

Surge arresters

Auxiliary transformer, 2-hanger, single bushing, 120 VAC secondary, steel tank, with internal weak link and wildlife protection

Two or four hole NEMA pads for primary connection

Wildlife covers
