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
