DAB7 series Miniature Circuit breaker(MCB)

image002.jpg

Miniature circuit breakers 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.

Design Features

image003.jpg 

Circuit breaker construction provides for two types of overcurrent protection that can essentially boost the safety of distribution and group systems.

image004.jpg 

Conducting parts are made of high quality electric copper.

image005.jpg 

Updated arc chute allows splitting the electric arc into numerous smaller arcs that contributes to its faster extinguishing.

New construction of the trip-free release mechanism (substantially reduced time of contact loss).
