Product descriptions from the supplier
Product Introduction
These pole fuse switches include separate terminal covers for in-coming and out-going conductors, thus making installation safer. Connectors included 2 x KG45, poles 1.The 160A Pole Fuse Switch Disconnector is a multi-functional low-voltage (LV) electrical component integrating switching, isolation, and fuse protection. With a rated current of 160A, it’s designed for pole-mounted installation in LV power distribution systems—common in industrial workshops, commercial buildings, and small-scale infrastructure grids. Its core role is to safely isolate circuits during maintenance, control load current on the pole, and rely on built-in fuses to interrupt overloads or short-circuit currents, protecting downstream equipment (e.g., motors, distribution panels) and ensuring grid stability.
Features
160A Rated Current for Targeted Loads：Optimized for 160A current capacity, it matches mid-range LV load scenarios (e.g., commercial HVAC systems, industrial auxiliary equipment) without overcapacity waste or underperformance risks, ensuring stable long-term operation.
Pole-Mounted Design for Space & Installation Efficiency：Tailored for pole-mounted setups, it saves cabinet space in switchgear and simplifies integration into overhead/vertical pole distribution networks. The compact structure also reduces on-site installation time and layout complexity.
Reliable Fuse-Based Fault Interruption：Relies on high-quality fuses (e.g., gG/gL type) to respond quickly to faults: when current exceeds the fuse rating, the fuse element melts to interrupt the circuit, avoiding prolonged abnormal current that damages equipment—no need for complex electronic trip units.
Safe Isolation Performance：Meets electrical safety standards for isolation (e.g., IEC 60947-3), with a clear "open" position indicator and mechanical interlocks (optional) to prevent accidental reconnection during maintenance. This ensures technicians can work on circuits safely.
Durable Construction for Harsh Environments：Housings and internal components use corrosion-resistant, arc-resistant materials (e.g., reinforced thermoplastics, copper alloys), enabling reliable operation in dusty, humid, or mild-vibration environments (common in industrial/commercial sites).

How to Judge, Detect and Troubleshoot Transformer Core Faults1. Hazards, Causes, and Types of Multi-Point Grounding Faults in Transformer Cores1.1 Hazards of Multi-Point Grounding Faults in the CoreUnder normal operation, a transformer core must be grounded at only one point. During operation, alternating magnetic fields surround the windings. Due to electromagnetic induction, parasitic capacitances exist between the high-voltage and low-voltage windings, between the low-voltage winding and the core, and between the core and the tank.
