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.

Frequently Asked Questions (FAQ)

QWhat is the main function of the HR series fuse-disconnector switch?
The switch provides isolation protection and overload/short-circuit protection in low-voltage electrical distribution systems, allowing safe manual switching and circuit disconnection.
QWhat is the operational difference between code suffix "0" and "1"?
Code suffix "0" designates a non-fused signal device type configured for fuse links with visual indicators, while "1" indicates a fused signal device type designed for fuse links with mechanical tripping mechanisms.
QWhat rated currents are available for this series?
Standard configurations support rated operational currents of 100A, 200A, 315A, 400A, and 630A across specified voltage ratings.
QWhat is the rated short-circuit breaking capacity?
The product line achieves a root mean square short-circuit breaking capacity rating of 50kA under specified test standards.
QCan these fuse-disconnectors be operated in both 2-pole and 3-pole configurations?
Yes, unit structures are manufactured in both 2-pole and 3-pole arrangements to accommodate various electrical grid setups.
