Product Description

 Chint NM8N series  NM8N-250S TM 200 4C moulded case circuit breaker  MCCB 

Product Description

1.General

The NM8N series moulded case circuit breaker is suitable for AC circuits with frequencies of 50/60Hz,  rated voltages up to AC 690V, and DC systems with rated voltages up to DC 1000V. It has a rated current range from 16A to 1600A. This circuit breaker provides protection against overload, short circuit, and undervoltage conditions. Additionally, it offers the same protection for infrequent motor starts.
 

The products offer power distribution protection, motor protection, residual current protection, and isolation.
 

The circuit breaker can be installed vertically or horizontally and supports both top and bottom line entry configurations.

 

2.Operading conditions 
 

2.1 Temperature:

Operating and storage temperature is -40°C~+70°C; the average value within 24 hours does not  exceed +35°C; when the ambient temperature is -40°C~+70°C, users need to consider derating or  temperature compensation whose details can be referred to in Sections 10.3 and 10.4.

2.2 Altitude: ≤ 2000m;

2.3 Pollution grade: Grade 3;

 

2.4 IP grade: IP40

2.5Environmental conditions:

At the mounting site, relative humidity should not exceed 50% at a maximum temperature of +40°C. Higher humidity is permissible at lower temperatures, such as 90% RH at +20°C. Special measures should be taken to prevent dew formation.
