Conforming to IEC 60947-3, this switch provides three operating positions — OFF (O), Source 1 (I), and Source 2 (C) — making it well suited for manual transfer between two power sources, generator changeover, and dual-supply selection in industrial and commercial electrical systems. With an impulse withstand voltage of 8kV, operational current ratings of 25A (AC-22A) and 20A (AC-23A) at up to 500V, and 25A \/ 11A respectively at 690V, the OT25F4C is appropriate for a wide range of load types and distribution voltages. Manufactured in Finland by ABB Oy and certified to CE and EAC standards, order code 1SCA104877R1001, this is a globally compliant, field-proven switching device. Procurement teams across the USA source ABB OT series change-over switches for panel-building, MRO, and generator integration projects. Electrical contractors and distributors in the UAE specify ABB OT25F4C units for building services, industrial panels, and power transfer applications.
