HR5 Fused Disconnect Switch with Visible Contacts

The HR5 Fused Disconnect Switch delivers reliable circuit protection and isolation for industrial systems, supporting 100-630A loads at AC400-660V with AC-22B/AC-23B utilization categories. This fused disconnect switch features 10le making capacity and 8le breaking capacity under 1.05Ue voltage, ensuring robust performance with 50kA short-circuit breaking capability. Designed for heavy-duty applications, the HR5 switch operates with 0.25-0.65 power factor and handles 3-5 switching cycles per fault condition. Its fused design combines manual control and overload protection, ideal for motor circuits and power distribution panels requiring safe isolation and fault interruption.
