Product Description

Overview

Product Details

Application

The breaker is mainly applied to infrequent changeover in a circuit with alternate current of 50/60Hz, rated working voltage of 415V and rated working current to 125A, and to the infrequent start of electric motor.

The breaker has overload, short circuit and undervoltage protection functions that can prevent the line and power unit from being damaged while protecting the possible fire danger and electric shock by the long-term failure of groud connection which fails to be detected by overcurrent protection.

Product certification and implementation standard:

  • Product certificate:CCC
  • Product certification standard:GB/T 14048.2, IEC60947-2,

GB/T 14048.1, IEC60947-1

Normal Working conditions:

  • Ambient temperature:-35℃~+70℃, the average within 24h shall not be more than +35℃. If the ambient temperature is higher than +40℃, the user needs to reduce the capacity.
  • Stored ambient temperature:-40℃~+75℃
  • Altitude:≤2000m
  • Pollution degree: 3
  • Its relative humidity at an ambient temperature of +40℃ should not exceed 50%. A higher relative humidity is allowed at a lower temperature. For example, the relative humidity at 20 ℃ can reach 90%, for frost dur to temperature change, the corresponding measures shoud be taken.


Packaging and storage:

  • Minimum packing quantity

1 piece / box

  • Products should be stored in the warehouse where there is ventilation. The relative humidity there should not exceed 80%, and the ambient temperature there is between -40℃ to +75℃. In addition, there should not be acidic, alkaline and corrosive gas in the air.
  • Products should not be deposited more than 3 years in the above mentioned conditions since the producing date.
