CHINT NH40 Series Isolator Switch NH40-63/100/160/250 3P 4P AC690V Load Disconnect Isolation Switch 63A~250A Low Voltage Main Isolator

Product Overview

CHINT NH40 series load isolation switch complies with GB/T14048.3 & IEC60947-3 international standards, applicable for AC 50Hz, rated voltage up to AC690V, rated current range from 63A to 3150A. Mainly used in industrial & civil power distribution cabinet for non-frequent manual circuit make/break and safe power isolation; specifications from 125A~630A allow frequent switching, NOT suitable for direct single motor startup. Available pole:3P/4P, current grades:63A/100A/160A/250A.

Key Product Features

  1. Flame Retardant Housing: High strength unsaturated polyester shell, excellent insulation & fire resistance, anti-aging for long-term cabinet use.
  2. Spring Energy Storage Mechanism: Independent spring accelerated structure realizes fast on/off action regardless of manual operating speed, effectively suppress electric arc.
  3. Double Break Rolling Contact: Parallel dual-break rolling contact with compression spring to maintain stable contact pressure, reduce contact ablation and heating.
  4. Clear ON/OFF Indicator: Distinct mechanical position mark for visible open/close status to confirm safe isolation gap for maintenance.

Application Scenario

Main incoming isolation of distribution cabinet, generator power switching, commercial & factory power panel, inverter front-end isolation switch for solar PV system.
