DAB7-63H series Miniature Circuit breaker(MCB)
Introduction
  | Miniature circuit breakers DAB7-63H 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.  | 
Advantages
?Two types of overcurrent protection – thermal and electromagnetic.
?High Breaker capacity 10KA
?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
  | Circuit breaker construction provides for two types of overcurrent protection that can essentially boost the safety of distribution and group systems.  | 
  | Conducting parts are made of high quality electric copper.  | 
  | Updated arc chute allows splitting the electric arc into numerous smaller arcs that contributes to its faster extinguishing.  | 
  | Welding deposition of silver-bearing composite on the contact block.  | 
  | Using buses (PIN, FORK) is possible.  | 
  | New construction of the trip-free release mechanism (substantially reduced time of contact loss).  | 
  | Double quenching grid at the arch chute output raises fire safety preventing combustion products from exposing.  | 
  | Boosted screw head dimension with cross-functional crest (+,–) helps to facilitate mounting and prevents the screws from falling out during the installation.  |
