SVM5H-320H 1000VAC MCCB

General

SVM5H series of moulded case circuit breaker is supplied with rated insulating voltage 1150V and used for circuit of A.C. 50Hz, rated operating voltage AC 1140V. (or below), rated operating current up to 630A for infrequent changing over and starting of the motors.

Products are widely used in new energy, photovoltaic (string type), electric power, industrial control, real estate, power supply, telecommunications, rail transit and other industries.

Equiped with the protection devices for over-current, short circuit and u ndervoltage, the products are capable of preventing damage of circuits and supply units. The products conforms to GB/T14048.2, IEC60947-2 stardands.

Normal Operating Conditions                                            

Altitude: ≤2000m  

Installation height 2000m ~ 5000m can be specially customized. The product needs to reduce the capacity to use.

Pollution Degree: 3 according to IEC 60947-1

Ambient Temp. (operating): -5 to 40 ℃

For the working conditions of -40~-5℃ ambient temperature, please inform us when ordering.

When the ambient temperature is higher than 40 ° C, the product should be used at reduced capacity.

Ambient Temp. (storage): -40 to 70 ℃

The average ambient temp. in 24 hours cannot exceed 35 ℃.

The relative humidity cannot exceed 50% @+40 ℃. A lower temperature can have a higher humidity. The relative humidity can reach 90% at 20 ℃, and corresponding measures should be taken for the condensation frost caused by the temperature change.
