Best quality Adjustable Circuit Breaker - DAB5 series Miniature Circuit breaker(MCB) – DaDa

>> Introduction

DAB5-63  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 DAB5-63 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° С.

· Updated wider engagement lever with improved contact area.

· Notches on terminal clamps provide for lowering thermal losses and boosting the mechanical stability of connection.
