Finder 6K.T0.0.000.1827 3-vaiheinen valvontarele, 400 V AC, 1 CO-kosketin, DIN-kisko

Three-phase motors can be damaged by phase loss, incorrect phase sequence, or voltage anomalies. The Finder 6K.T0.0.000.1827 monitoring relay continuously checks the supply and disconnects the load when a fault is detected.

Who is it for

Maintenance engineers and panel builders who need reliable protection for pumps, compressors, conveyors and other three-phase equipment in industrial environments.

Main features

• Monitors phase sequence, phase loss, undervoltage, overvoltage and asymmetry
• 1 changeover contact (1 NO + 1 NC) with AgNi contact material
• Adjustable start-up delay (0.5–60 s) and trip delay (0.1–30 s)
• Thresholds: undervoltage 80–95% UN, overvoltage 105–120% UN, asymmetry 5–20%
• DIN rail mounting, 35 mm width (2 modules)
• Operating temperature -20 to +60 °C

Specifications

• Nominal supply voltage: 3 x 400 V AC (380–415 V AC)
• Maximum operating voltage: 690 V AC
• Rated contact current: 6 A at 250 V AC (AC1)
• Protection degree: IP40 housing, IP20 terminals

Tips

Set the asymmetry threshold carefully to avoid nuisance tripping on motors with inherent voltage imbalance. Use the start-up delay to bypass inrush conditions.
