Product Details

NS 250A 3P MCCB Moulded case circuit breaker with CE

Product Description

The design of NS series of MCCB reflects the latest current limiting principle and manufacturing technology, characterized by compact structures, full modularization, high breaking, and zero flashover. Circuit breaker is equipped with overload, short-circuit and undervoltage protection device, so as to protect the circuit and power supply equipment from damage.

Explaination:

Ui: rated insulation voltage.

Uimp: rated impulse withstand voltage.

Ue: rated operational voltage.

icu: rated ultimate short-circuit breaking capacity.

Conditions:

the altitude below 2000m.

the ambient temperature between 40℃ and -5℃.

It can withstand the impact from humid air, salt spray, oil mist and mold.

In places with no danger of explosion, no conductive dust, and no substance enough to corrode metal or damage the insulation.

In places with no rain and snow erosion.
