DAB7 series Miniature Circuit breaker(MCB)
| 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. |
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
| 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. |
