Introduction Miniature circuit breakers
NOVA DAB7-63 are intended for providing automatic power
source cut-off under excess currents.They are recommended for use
in group panels (apartment and floor) and distribution boards of
residential, domestic, public and administrative buildings.64 items
per 8 rated currents ranging from 6 to 63 A.This MCB has been
obtained ASTA, SEMKO,CB,CE certificate.Advantages Two types
of overcurrent protection - thermal and electromagnetic.Independent
contact position indicator.DIN rail latch with a double fixed
position.Wide range of operating temperatures from -40 to +50°
С.Wide engagement lever with improved contact area.Notches on
terminal clamps lower thermal losses and boost the mechanical
stability of connection. Technical Features For
