HRWK series is a low voltage fused isolation switch designed for 50Hz AC distribution systems with rated voltage of 0.5kV and below, with circuit isolation and short circuit protection functions.
HRWK series is a low voltage fused isolation switch designed for 50Hz AC distribution systems, rated voltage 0.5kV and below, and has circuit isolation and short circuit protection functions.
Functions
Circuit Isolation: Provides visible break points for safe servicing.
Short Circuit Protection: Built-in fuse quickly interrupts short circuit current, protecting transformers and low voltage lines.
No-Load Switching: Supports switching on and off of lines or low voltage sides of transformers under no-load conditions.
Typical scenario
- Power distribution system: protecting the low voltage side of the transformer and switching lines.
- Industrial power supply: Installation in low-voltage distribution cabinets for use in non-hazardous areas.
- In the field of new energy: insulation and protection of low-voltage circuits in photovoltaics and wind energy.
HRWK series disconnect switches are widely used in low-voltage outdoor distribution cabinets due to fuse integration, high protection degree and low maintenance cost. The selection must be fully evaluated based on current power, environmental conditions and functional requirements
