Description

 

LV withdrawable cabinet MBLOKSET is a modular, multi-functional low voltage distribution cabinet It is used in all the low voltage systems in need of high reliable fields in metallurgy, petroleum. Chemical, industrial and mining enterprises and infrastructure areas: power distribution and motor control system.

The cabinet structure adopted by MBLOKSET is highly flexible. According to the needs of customers or different applicable occasions, the cabinet can be installed with a variety of models and specifications of components; According to different electrical equipment, a variety of types of feeder units can be installed in the same row of cabinet or the same cabinet. For example: feed circuit and motor control circuit can be mixed together.

A robust architecture, type-tested, standardized modules devices work together to improve functionality, safety, continuity of supply and installation reliability even in the most difficult conditions.

  • All components and accessories are designed and manufactured to rigorous quality standards
  • Compatibility between switchboards, functional units, and built-in devices is tested and validated
  • All components have outstanding electrical and mechanical consistency and electromagnetic compatibility (EMC)

Normal operating conditions:

  1. Ambient temperature: not exceed +40℃, average temperature within 24h not exceed +35℃;
  2. Air should be clean. Air relative humidity should not exceed 50% at +40℃, higher relative humidity is permissible at lower temperature condition, for instance, 90% at +20℃, please take measures for the condensation produced on the product caused by temperature change occasionally;
  3. Altitude should not exceed 2000m;
