DAB6 series Miniature Circuit breaker(MCB)
Introduction
DAB6-63 are intended for protecting distribution and group systems having different loads:
- electric appliances, lighting – V characteristic switches;
- drives with moderate starting currents (compressor, fan group) - C characteristic switches;
- drives with high starting currents (hoisting mechanisms, pumps) - D characteristic switches;
Miniature circuit breaker DAB6-63 are recommended for use in electrical distribution panels of residential and public buildings.
Advantages
?Two types of short circuit protection.
?Wide range of operating temperatures from –40 to +50°c.
?Updated wider engagement lever with improved contact area.
?Notches on terminal clamps provide for lowering thermal losses and boosting the mechanical stability of connection.
Design Features
| Circuit breaker construction provides two types of overload and short circuit protection that can essentially boost the safety of distribution and group systems. |
| Welding deposition of silver-bearing composite provides boosting the contact block’s wear-resistance and lowering the transient one. |
| Unified casing with the possibility to connect supplementary devices does not require disassembling. Independent installation is possible. |
| Updated wider engagement lever with improved contact area facilitates commutation process. |
| Boosted screw head dimension with cross-functional crest (+,–) helps to facilitate mounting and prevents the screws from falling out during the installation. |
| Notches on terminal clamps allow lowering thermal losses and boosting the mechanical stability of connection. |
| Plexiglas fitting protects the thermal cut-off mechanism from the factory settings changing. |
