Product Specifications
Product Description
MEBA NF series thermal magnetic type Air Circuit breaker(ACB), developed from Mitsubishi type, included NF-CS, NF-SS, NF-CP, NF-SP, NF-HP, NF-CW series, rated working voltage 690V, 50Hz or 60Hz, and rated working current from 3A to 800A. It mainly used in distributing electric energy and protect the electrical circuit and power equipment from damages caused by overload, short circuit or under-voltage in the distribution network. It complies with IEC60947-2 and GB14048.2 standards.
Working Conditions and Mounting Environments
1. The altitude should be less than 2000m
2. The ambient medium temperature should within -5 to +40
3. This moulded case circuit breaker is resistant to moisture, salt fog, nuclear radiation, and mildew
4. The maximum tilt angle is 22.5
5. MCCB can still work reliably if the product is subjected to vibration from ships or earthquakes(4G)
