Schneider Electric 50439 VigiPacT IA80 Closed Toroid – 80 mm Inner Diameter, 160 A Rated Current, 1/1000 Ratio

제품 설명

The Schneider Electric 50439 is a closed toroid from the VigiPacT range, designed as a residual current sensor for type A earth leakage protection and monitoring. With an 80 mm inner diameter and a rated operational current of 160 A, it is compatible with VigiPacT RH10M to RH197P relays and Vigilohm insulation fault locators. The transformer ratio of 1/1000 enables precise measurement of residual currents for reliable fault detection. It withstands a rated short-time current of 85 kA for 0.5 seconds and features reinforced insulation with an overvoltage category IV rating. The toroid is suitable for fixed mounting on cables, backplates, or DIN rail, and operates reliably from -35 °C to +70 °C in industrial and commercial power distribution systems.

기본 사양

• Type A Residual Current Sensing: Detects AC and pulsating DC residual currents for comprehensive earth leakage protection in modern electrical installations.
• 80 mm Inner Diameter: Accommodates cables with a total outer diameter up to 40 mm and a maximum cross-section of 95 mm² per phase, simplifying retrofitting in existing switchgear.
• 160 A Rated Operational Current: Supports continuous monitoring of circuits up to 160 A, suitable for feeder and branch protection in industrial and commercial distribution boards.
• 1/1000 Transformer Ratio: Provides precise and consistent residual current measurement for accurate coordination with VigiPacT relays.
• 85 kA/0.5 s Short-Time Withstand: Withstands high fault currents without damage, ensuring reliability in demanding power distribution environments.
• Reinforced Insulation (Overvoltage Category IV): Offers enhanced dielectric strength and safety for use at the origin of installations and in harsh electrical environments.
• Versatile Mounting Options: Supports fixed mounting on cables, plain or slotted backplates, and clip-on DIN rail mounting for flexible installation in various panel configurations.
