Product overview
The OSM is NOJA Power’s outdoor automatic circuit recloser family. It combines vacuum interruption, solid-dielectric insulation and an RC-series controller for protection, measurement, automation and communications.
Verified configuration
The official product family spans distribution voltage classes up to 38 kV and references IEC 62271-111 and IEEE C37.60. Exact continuous current and interrupting duty vary by OSM model, so those fields remain unpopulated in this family-level record.
Engineering significance
OSM is relevant to feeder automation, renewable interconnection and reliability improvement where reclosing, sectionalising and remote control are required without SF6 insulation.
Specification caution
Select by exact model and system grounding. Verify BIL, interrupting and making duty, CT performance, controller firmware, communications, auxiliary supply, mounting and environmental options in the current official catalogue.
