Automatic Circuit Breaker CHINT NM8-630S 3P 500A 70kA (thermal and magnetic)

CHINT NM automatic circuit breaker in a moulded case from 16A to 1250A

tripping capacity from 50 kA to 100 kA

Advantages:

• Up to 20,000 tripping cycles under proper operating conditions
• Two types of trip units — thermal and magnetic
• React to all current deviations (both overloads and short circuits)
• Wide tripping capacity range
• Can be used to protect a wide range of objects and equipment

CHINT automatic circuit breakers protect equipment and wiring from voltage surges and dips, overloads, and short circuits. Models belonging to the NM8 series can be divided into 3 classes by tripping capacity. The standard class is denoted by the letter "S" in the model name. The letter "H" indicates a high tripping capacity class. Current-limiting circuit breakers have the letter "R" in their name. If the NM8 series breaker has only a magnetic trip unit, the name is supplemented with the designation "M". If an electronic trip unit is present, the model name is supplemented with the letter "S".

The CHINT NM8 automatic circuit breaker can be used as an alternative to moulded-case circuit breakers from the following series:

• ABB Tmax T and Tmax XT
• Schneider-Electric Compact NSX — NA
• Siemens VL
• KEAZ VA57 and OptiMat
• VA88, VA-99
• CHINT circuit breakers can be purchased with a 1-year warranty on the 220 Volt website.
