Product Description

Introduction
DAB6-63
The DAB6-63 series is meticulously engineered to safeguard distribution and group systems catering to various load requirements:
- Electric appliances, lighting - V characteristic switches;
- Drives with moderate starting currents (e.g., compressors, fan groups) - C characteristic switches;
- Drives with high starting currents (e.g., hoisting mechanisms, pumps) - D characteristic switches;
M
iniature circuit breaker DAB6-63
is ideally suited for installation in the electrical distribution panels of both residential and public buildings, ensuring optimal performance and safety.

Advantages

• Provides dual short-circuit protection for enhanced safety.
