Dold BC9190N.11 AC50HZ 230V 0,15-3S, Short-time Voltage Drop Relay, sku: 0054920

Monitoring of voltage systems to detect auto reclosing as e.g. generated by the energy supplier in the case of flash-overs or switching procedures. It is possible that in control circuits some of the devices are resetted during auto reclosing and some not. Because of this uncontrollable situations may occur.

• According to IEC/EN 60255-1
• Fast detection of undervoltage and phase failure in AC voltage systems
• Detects voltage drops (reaction time ≤ 20 ms)
• Response value 0.8 or 0.7 UN selectable by wire link
• Without auxiliary supply
• De-energized on trip
• LED indicator for contact position
• Adjustable operate delay after return of voltage
• As option adjustable fleeting on make pulse after return of voltage (variant BC 9190N.11/001)
• 1 changeover contact
• Wire connection: also 2 x 1.5 mm2 stranded ferruled (isolated), DIN 46 228-1/-2/-3/-4 or 2 x 2.5 mm2 stranded ferruled DIN 46 228-1/-2/-3/-4
• Width 22.5 mm
