The DAM2 series molded case circuit breaker is designed for reliable power distribution protection in industrial applications. These MCCBs feature compact dimensions, high breaking capacity, and vibration resistance suitable for both land and marine installations.
These circuit breakers are rated for AC 50Hz/60Hz systems with working voltage up to 690V and insulation voltage of 800V. The DAM2 series provides comprehensive protection against overload, short-circuit, and under-voltage conditions while supporting infrequent motor starting operations.
The breakers can be installed in either vertical or horizontal orientation and meet IEC60947-2 standards for low-voltage switchgear. Multiple configurations are available including different pole counts (2P, 3P, 4P), current ratings, and breaking capacity levels (L, M, H types).
Key technical features include:
- Instantaneous trip setting: 10In±20% (distribution) or 12In±20% (motor protection)
- Wide ambient temperature range: -5°C to +40°C
- Suitable for altitudes up to 2000m
- Pollution degree 3 rating
The DAM2 MCCB series offers flexible accessory options including shunt releases, undervoltage releases, auxiliary contacts, and motorized operating mechanisms. These components enable remote operation and monitoring capabilities for advanced power distribution systems.
Available current ratings include:
- DAM2-63: 6A to 63A
- DAM2-100: 16A to 100A
- DAM2-250: 100A to 250A
- DAM2-400: 225A to 400A
- DAM2-630: 400A to 630A
- DAM2-800: 630A to 800A
- DAM2-1250: 800A to 1250A
