Product Description
The MKB3E series electronic moulded case circuit breakers are designed for AC 50Hz/60Hz circuits with:
- Rated insulation voltage: 1000V
- Rated operating voltage: 400V and below
- Rated operating current up to 1250A
- Suitable for infrequent switching and motor starting
Key Features
- Comprehensive protection functions: overload long delay inverse time, short circuit short delay inverse/definite time, short circuit instantaneous, under voltage
- Optional residual current and phase loss protection
- Precise protection characteristics improve power supply reliability
- Z/B type controllers feature communication interface for remote monitoring
- Two breaking capacity types: L-type (standard) and M-type (medium)
- Compact design with high breaking capacity and vibration resistance
- Flexible installation: vertical (upright) or horizontal (transverse)
- Isolation function (symbol: _/)
- Allows reverse wiring
