This Compact INV400 is a 4P non-automatic switch-disconnector with visible break, red rotary handle and yellow front. It is suitable for isolation with positive contact indication, as defined by IEC 60947-1 and IEC60947-3 standards. The operational current is 400A at 415VAC in categories AC21A, AC22A and AC23A. The rated voltage is 690VAC 50/60Hz or 250VDC. Compact INV range allows the visible break of the main contacts through a transparent cover. It can be used as an emergency-off device. For easy identification, it uses special colours stipulated by the standards. The red rotary handle is designed to offer easy operation and high performance in interruption of currents. Compact INV400 is a class II insulation level front-face device as per IEC 60664 standard.
