Model NO. | Pole fuse switch disconnector for protecting in LV-networks |
Rated frequency | 50/60Hz |
Series | SZ |
The Pole Fuse Switch Disconnector is a critical protective component designed specifically for low-voltage (LV) networks (typically up to 1kV). Mounted on poles in overhead or vertical distribution setups, it integrates switching, isolation, and fuse-based protection to safeguard LV networks from electrical faults. Its primary role is to interrupt overloads and short circuits, isolate faulty sections, and control power flow—ensuring the stability of residential, commercial, and light industrial LV grids while protecting conductors, transformers, and connected equipment.
LV Network-Specific Protection:Optimized for low-voltage environments (≤1kV), it matches the current and voltage demands of LV networks, providing precise protection without over-engineering. Ideal for grids powering homes, offices, and small-scale industrial loads.
Triple Functionality:Combines three key roles: manual switching (to control circuit on/off), safe isolation (for maintenance, preventing electric shock), and fuse-triggered fault interruption (fuses melt to stop overloads/short circuits). Eliminates the need for separate components.
Pole-Mounted Design for LV Grid Compatibility:Engineered for pole installation, it fits seamlessly into overhead LV networks—common in suburban and rural areas. The compact, weather-resistant build minimizes space usage while withstanding outdoor conditions (rain, dust, temperature swings).
Rapid Fault Response:Fuses react instantly to abnormal currents, interrupting the circuit before damage spreads to other network components (e.g., distribution transformers, consumer meters). This limits downtime and reduces repair costs.
