High-Quality HR17 Fused Isolation Switch For High Current Suppliers, Factory

The HR17 Fused Isolation Switch delivers robust circuit protection and isolation for industrial power systems, supporting 40A-800A loads at AC400-1000V with 1000V insulation and 12kV impulse withstand. This fused isolation switch complies with AC-21B/22B/23B utilization categories, ensuring reliable performance for motor control and resistive loads. Featuring 50kA short-circuit current rating (105kA peak) and low phase-breaking power consumption (5-48W), the HR17 switch combines fused protection with manual isolation in one compact unit. Ideal for high-voltage applications, it provides visible disconnect assurance and meets IEC60947-3 standards for industrial safety and durability.
